Microchip announced a new family of power conversion controllers and its first ever family of power MOSFET devices. This new pulse width modulation (PWM) controller and complementary family of low-figure of merit (FOM) MOSFET products combine to support high-efficiency DC-DC power conversion designs covering a broad array of consumer and industrial applications.
The MCP19035 is a small, analog-based PWM controller family with integrated synchronous MOSFET drivers offering excellent transient performance. The devices operate over a wide 4,5-30 V d.c. range, have a 300 kHz switching frequency, and offer a factory adjustable dead-time setting, allowing designers to optimise performance across a wide selection of MOSFET devices.
When combined with Microchip’s MCP87xxx MOSFETs, or any low-FOM MOSFET, the MCP19035 family produces 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. The MCP87022, MCP87050 and MCP87055 offer on-state resistance of 2,2 mΩ, 5,0 mΩ and 5,5 mΩ respectively.
