Microchip Technology Inc. (NASDAQ: MCHP), 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, 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 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 family of PWM controllers expands the range of choices for design engineers in solving their application power-conversion needs,” said Bryan J. Liddiard, vice president of marketing with Microchip’s Analog & Interface Products Division. “Its broad operating range and integrated, high-power synchronous driver supports high-efficiency, power-dense solutions that require a fast, analog-based controller. They combine with Microchip’s first-ever, high-speed MOSFET offerings to form a fast and efficient power-conversion solution, yielding efficiencies exceeding 96%.”
The MCP87xxx MOSFET family also complements Microchip’s existing portfolio of SMPS-focused PIC® microcontroller and dsPIC33 “GS” digital signal controllers. Microchip’s MCP14700 synchronous MOSFET driver is ideally suited for driving high-speed, low-FOM MOSFETs. When driven by a microcontroller, the two form a flexible, high-performance power-conversion solution.
Development Tool Support
The MCP19035 300 kHz Evaluation Board (part # ADM00434, $45.99) for the MCP19035 family is available now, via any Microchip sales representative and on microchipDIRECT.
