Power-conversion controllers and power MOSFETs deliver high efficiency

A new family of Pulse Width Modulation (PWM) controllers and complementary family of low Figure of Merit (FOM) MOSFET products combine to support high-efficiency dc/dc power-conversion designs.
The MCP19035 is a small, analog-based PWM controller family with integrated synchronous MOSFET drivers offering outstanding transient performance. The MCP19035 devices operate over a wide 4.5 to 30 Vdc range, have a 300 kHz switching frequency, and offer a factory-adjustable dead-time setting, allowing designers to optimize the performance across a wide selection of MOSFET devices. The MCP19035 family, when combined with MCP87xxx MOSFETs, or any low-FOM MOSFET, produce high-efficiency (> 96%) dc/dc power-conversion solutions.

The MCP87xxx family of high-speed MOSFETs offers very low FOMs and is packaged in industry-standard 5 x 6 mm and 3.3 x 3.3 mm PDFN packages. Releasing are the MCP87022, MCP87050, and MCP87055 devices, which offer on-state resistance of 2.2, 5.0, and 5.5 mΩ, respectively. These new MOSFETs enable high-efficiency power-conversion designs.
