Power Integrations TOPSwitch-JX Series Integrated Off-Line Switchers with EcoSmart™ Technology
Power Integrations TOPSwitch-JX Series Integrated Off-Line Switchers with EcoSmart™ Technology each consist of a 725V power MOSFET, high-voltage switched current source, multi-mode PWM control, oscillator, thermal shutdown circuit, fault protection, and other control circuitry, cost effectively incorporated onto each monolithic device. Power Integrations TOPSwitch-JX Series Integrated Off-Line Switchers employ EcoSmart™ Technology which offers no-load consumption below 100mW at 265VAC, up to 750mW standby output power for 1W input at 230VAC, energy efficiency over entire load range, and is ideal for applications from 10W to 245W. TOPSwitch-JX offers high design flexibility for low system cost, with multi-mode PWM control which maximizes efficiency at all loads, accurate programmable current limit, optimized line feed-forward for line ripple rejection, frequency jittering to reduce EMI filter cost, and fully integrated soft-start for minimum start-up stress. The 132kHz operation reduces transformer and power supply size, with a 66kHz option for highest efficiency requirements, and the 725V-rated MOSFET simplifies meeting design derating requirements. Typical applications for the Power Integrations TOPSwitch-JX Series include notebook or laptop adapters, printers, LCD monitors, and audio amplifiers.
Power Integrations HiperTFS™ Family Combined Two-Switch Forward & Flyback Power Supply Controllers
Power Integrations HiperTFS™ Family Combined Two-Switch Forward & Flyback Power Supply Controllers each incorporate both a high-power, two-switch-forward converter and a mid-power flyback (standby) converter into a single, low-profile eSIP™ power package. The single chip solution provides the controllers for the two-switch-forward and flyback converters, high- and low-side drivers, all three of the high-voltage power MOSFETs, and eliminates the converter's need for costly external pulse transformers. Power Integrations HiperTFS™ Family Combined Two-Switch Forward & Flyback Power Supply Controllers are ideal for high power applications that require both a main power converter (two-switch forward) up to 414 W, and standby converter (flyback) up to 20 W. HiperTFS includes Power Integrations' standard set of comprehensive protection features, such as integrated soft-start, fault and over-load protection, and hysteretic thermal shutdown. HiperTFS utilizes advanced power packaging technology that simplifies the complexity of two-switch-forward layout, mounting, and thermal management, while providing very high power capabilities in a single compact package. The controllers operate over a wide input voltage range, and can be used following a power-factor correction stage such as HiperPFS.
Power Integrations HiperPFS™ Family High Power PFC Controllers
Power Integrations HiperPFS™ Family High Power PFC Controllers each incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver, and high voltage power MOSFET in a single, low-profile eSIP™ power package that is able to provide near unity input power factor. These controllers eliminate the PFC converter's need for external current sense resistors and the power loss associated with those components, and leverage an innovative control technique that adjusts the switching frequency over output load, input line voltage, and even input line cycle. This control technique is designed to maximize efficiency over the entire load range of the converter, particularly at light loads, and also significantly minimizes the EMI filtering requirements due to its wide-bandwidth spread spectrum effect. Power Integrations HiperPFS™ Family High Power PFC Controllers include Power Integrations' standard set of comprehensive protection features, such as integrated soft-start, UV, OV, brown-in/out, and hysteretic thermal shutdown. They also provide cycle-by-cycle current limit for the power MOSFET, power limiting of the output for overload protection, and pin-to-pin short-circuit protection.
Power Integrations LinkZero-LP Zero No-Load Consumption Integrated Off-Line Switcher
Power Integrations LinkZero-LP Zero No-Load Consumption Integrated Off-Line Switcher is an upgrade to the LinkSwitch-LP, the industry's lowest component count charger/adapter and standby power switcher IC. It incorporates new technology which enables the device to automatically enter into and wake up from no-load mode while taking less than 5mW from the AC power. Power Integrations LinkZero-LP Zero No-Load Consumption Integrated Off-Line Switcher comprises a 700V power MOSFET switch with a power supply controller on the same die. Unlike conventional PWM (pulse width modulation) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of the following circuits: an oscillator, feedback (sense) 5.85V regulator, BYPASS pin under/overvoltage protection, over-temperature protection, frequency jittering, current limit, leading edge blanking BYPASS pin clamp in power down, and bypass mode. The controller includes a proprietary power down mode that automatically reduces standby consumption to levels that are immeasurable on most power meters.
Power Integrations FullPak X-Series Rectifiers
Power Integrations 8A and 10A FullPak X-Series rectifiers target high performance power supply applications where the added isolation of a FullPak is needed. Typical end product use for Power Integrations FullPak X-Series rectifiers includes Plasma and LCD TV power supplies and Medical power supplies. Along with standard TO-220 and D2Pak devices, these Power Integrations Semiconductor FullPak X-Series rectifiers fill out the X-Series product line, giving designers unprecedented choices in high performance 600V diodes.
Power Integrations Dual Diode X-Series Rectifiers
Power Integrations LXA16T600C, LXA12T600C, and LXA08T600C
Dual Diode X-Series rectifiers satisfy the emerging marketplace for
Interleaved and Bridgeless Power Factor Correction Boost converters.
These Dual Diode X-Series rectifiers give extremely low switching
loss in a single package that will replace two diodes from other
manufacturers with higher performance and lower device and manufacturing
cost. The reduced component count will also increase quality and
reliability. Power Integrations Dual Diode X-Series rectifiers
are available in dual 4A, dual 6A, and dual 8A versions covering power
ranges from 200-1200W in a single package.
Power Integrations 600V H-Series PFC Rectifiers
Power Integrations H-Series PFC rectifiers give the lowest switching loss of any silicon 600V diode. H-Series rectifiers, available in 3A, 5A, 8A, and 12A current ratings, are drop-in replacements for more expensive Silicon Carbide (SiC) diodes. In addition to extremely low switching loss, these Power Integrations rectifiers exhibit a very soft recovery characteristic that dramatically reduces EMI. This low EMI profile makes Power Integrations H-Series rectifiers the perfect choice for medical equipment power supplies. Other typical applications include AC-DC power supplies, solar inverters and boost, motor drives, and audio equipment.
