PWM Controller with Integrated MOSFET Drivers, and High-Speed MOSFETs
Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today 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. Together, these two families demonstrate a significant expansion of Microchip's commitment to enabling higher-voltages and higher efficiencies, as well as the industry trend toward smaller, power-conversion systems.
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 - 30Vdc range, has a 300 kHz switching-frequency, and offers 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 Microchip's MCP87xxx MOSFETs, or any low-FOM MOSFET, 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 5x6 mm and 3.3x3.3 mm PDFN packages. Releasing are the MCP87022, MCP87050, and MCP87055 devices, which offer on-state resistance of 2.2mΩ, 5.0mΩ, and 5.5mΩ, respectively. These new MOSFETs enable high-efficiency power-conversion designs.
The MCP19035 and MCP87xxx families are available now for sampling and volume production. The MCP19035 family is offered in a 3x3 mm 10-pin DFN package, with prices starting at $1.12 each in 5,000-unit quantities.
The MCP87022 and the MCP87050 are offered in a 5x6 mm 8-pin PDFN packages and the MCP87055 is available in a 3.3x3.3 mm 8-pin PDFN package. 5,000-unit pricing starts at $0.96, $0.45, and $0.39, respectively.
