Microchip Introduces High-Voltage Analog Buck PWM Controller with Integrated MOSFET Drivers, and High-Speed, Low-Figure of Merit MOSFET Family
Nov. 13, 2012 08:14 AM
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.
This board includes Microchip’s new MOSFETs. Complementing the MCP87xxx
MOSFET family release is an Excel-based Loss Calculator with user guide,
which are also available now.
Packaging, Pricing & Availability
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 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.
