Power Integrations HiperTFS-2 Power Controllers

Power Integrations HiperTFS-2 power controllers incorporate a high-power two-switch-forward converter and a mid-power flyback (standby) converter into a single, low-profile eSIP power package. This 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. The HiperTFS-2 is ideal for high power applications that require both a main power converter (two-switch forward) up to 586 W peak, and a standby converter (flyback) up to 20 W. Power Integrations HiperTFS-2 power controllers operate over a wide input voltage range, and can be used following a power-factor correction stage such as HiperPFS.

Power Integrations LYTSwitch-4221-28 High Power LED Drivers

Power Integrations LYTSwitch-4221-28 high power LED drivers feature a wide dimming range and fast start-up, even when turning-on from a low conduction angle and easily meet international requirements for THD and harmonics. Output current is tightly regulated with better than ±5% CC tolerance1. Efficiency of up to 92% is achieved in typical applications. LYTSwitch-4 drivers provide excellent turn-on characteristics for leading-edge and trailing-edge TRIAC dimming applications. LYTSwitch-4 ICs are highly integrated and employ a primary-side control technique that eliminates the optoisolator and reduces component count. This allows the use of low-cost single-sided printed circuit boards. Combining PFC and CC functions into a single-stage also helps reduce cost and increase efficiency. The 132 kHz switching frequency permits the use of small, low-cost magnetics. Power Integrations LYTSwitch-4 high power LED drivers do not use primary-side aluminum electrolytic bulk capacitors which greatly extended driver lifetime, especially in bulb and other high temperature applications.

Power Integrations CHY100 Charger Interface ICs

Power Integrations CHY100 charger interface ICs are low-cost, high-voltage, dedicated charging port (HVDCP) interface ICs for the Quick Charge 2.0 specification. CHY100 incorporates all necessary functions to add Quick Charge 2.0 capability to Power Integrations’ switcher ICs such as TOPSwitch or TinySwitch and other solutions employing traditional feedback schemes. CHY100 supports the full output voltage range of either Class A or Class B. Optionally Class B can be inhibited for protecting the battery charger from accidental damage. CHY100 automatically detects whether a connected Powered Device (PD) is Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD not compliant to Quick Charge 2.0 is detected the CHY100 disables output voltage adjustment to ensure safe operation with legacy 5V only USB PDs.

The start-up and operating power are derived directly from the voltage on the DRAIN pin. This eliminates the need for a bias supply and associated circuitry and allows low-cost discrete inductors to be used. The fully integrated auto-restart circuit in the LYTSwitch-0 family safely limits output power during fault conditions such as short-circuit or open-loop, reducing component count and lower system cost.

Power Integrations Qspeed™ Advanced Diodes

Power Integrations Qspeed™ Advanced Diodes combine an extremely low reverse recovery charge (QRR) with a very soft recovery waveform. Together, these features help designers improve the performance of their power conversion circuits. Three versions are currently available.

The LYTSwitch family supports a wide selection of TRIAC dimmers, providing excellent turn-on characteristics for leading-edge and trailing-edge TRIAC dimming applications. This results in drivers with a wide dimming range and fast start-up, even when turning-on from a low conduction angle.
