Microchip’s new buck PWM controller with high-speed low-FOM MOSFETs offer higher voltage, density and efficiency for DC/DC power conversion

For the first time, you can combine a high-speed, low-FOM MOSFET with Microchip’s new analogue-based PWM controller; or use them with Microchip MOSFET drivers and SMPS-optimised microcontrollers and digital signal controllers, for smaller, more efficient and higher voltage DC/DC power conversion.

DC/DC power-conversion efficiency can be pushed above 96% by driving Microchip’s new high-speed low-FOM MCP87xxx MOSFETs, with the analogue based MCP19035 PWM controller with integrated synchronous MOSFET drivers.  Alternatively, combine MCP87xxx MOSFETs with an MCP14700 synchronous driver and any SMPS-optimised PIC microcontroller or dsPIC33 “GS” digital signal controller, to create flexible, high-performance power-conversion solutions.

New high-voltage analogue buck PWM controller

With integrated synchronous MOSFET drivers, outstanding transient performance and a 300 kHz switching frequency, the MCP19035 high-voltage analogue buck PWM controller operates over a wide voltage range from 4.5 to 30Vdc. It also features factory-adjustable dead-time setting for optimising performance across a wide range of MOSFETs.

High-speed, low-FOM MOSFETs

Microchip’s first power MOSFETs, the MCP87022, MCP87050, and MCP87055, enhance power-conversion space efficiency and save board space with on-state resistance of 2.2mO, 5.0mO, and 5.5mO, respectively, and industry-standard 5 x 6 mm or 3.3 x 3.3 mm PDFN packages.
