Microchip's MCP16311/2 High-Efficiency Synchronous Step-Down Regulator is a compact, high-efficiency, fixed frequency, synchronous step-down DC-DC converter in a 8-pin MSOP, or 2 x 3 TDFN package that operates from input voltage sources up to 30V. Integrated features include a high-side and a low-side switch, fixed frequency Peak Current Mode Control, internal compensation, peak-current limit and overtemperature protection. The MCP16311/2 provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation. High-converter efficiency is achieved by integrating the current-limited, low-resistance, high-speed low-side and high-side switches, and associated drive circuitry. The MCP16311 is capable of running in PWM/PFM mode. It switches in PFM mode for light load conditions and for large buck conversion ratios. This results in a higher efficiency over all load ranges. The MCP16312 is running in PWM mode-only, and is recommended for noise-sensitive applications.
Microchip MCP1643 1MHz Synchronous Boost LED Constant Current Regulator is optimized to drive one LED with constant current that operates from one and two-cell alkaline and NiMH/NiCd batteries. This Microchip device can also drive two red/green/yellow series connection LEDs. Low-voltage technology allows the regulator to start up without high-output voltage and load-current overshoot from a low 0.65V input. The device features a typical peak input current limit of 1.5A. High efficiency is accomplished by integrating the low resistance N-Channel Boost switch and synchronous P-Channel switch. All compensation and protection circuitry are integrated to minimize external components. MCP1643 features an output overvoltage protection that limits the output voltage to 5.0V typical, in case the LED fails or output load is disconnected. MCP1643 is ideal for use in a variety of applications, including one- and two-cell Alkaline and NiMH/NiCd portable LED lighting products, LED flashlight and head lamps, rechargeable flashlights, wall LED lamps with motion detectors, and more.Learn More About MCP1643 LED Constant Current Regulator
Microchip's MCP19035 High-Speed Synchronous Buck Controllers are an application-optimized, high-speed synchronous buck controller that operates from input voltage sources up to 30V. This controller implements a voltage-mode control architecture with a fixed switching frequency of 300kHz. The high-switching frequency facilitates the use of smaller passive components, including the inductor and input/output capacitors, allowing a compact, high-performance power supply solution. The MCP19035 implements an adaptive anti-cross conduction scheme to prevent shoot-through in the external power MOSFETs. Further more, the MCP19035 offers multiple dead-time options, enabling an additional degree of optimization, allowing a higher efficiency power supply design. The MCP19035 controller is intended to be used for applications providing up to 20A of output currents across a wide input voltage range, up to 30V.Learn More About MCP19035 High-Speed Synchronous Buck Controllers

Microchip Technology Intelligent Analog PIC reduces the system cost, saves board space, and improves the performance of the design through increased throughput, and transfer of ADC data via UART or SPI. On products with DMA, the data is directly transferred to the RAM to be processed in parallel. Each analog module can be individually turned on or off when needed. DMA enabled DACs require no processor overhead for even faster responses. Integrated buffered DACs eliminate the need for an external buffer. DAC can be used as input or reference to Op Amp, Comparator, or ADC. Op Amp can be configured for either lowest power consumption or highest speed. MCU internal voltage references can be used as references for integrated analog components. CTMU can be used as a constant current source for sensors.
