Microchip houses synchronous buck MOSFET drivers in tiny packages

Chandler, Ariz.—Aiming to provide maximum efficiency in a small footprint, Microchip Technology Inc. is housing its MCP14628 and MCP14700 synchronous Buck MOSFET drivers in small 8-pin SOIC and 3 mm x 3 mm DFN packages.

The MCP14628 and MCP14700 devices drive two N-Channel MOSFETs arranged in a non-isolated, synchronous Buck converter topology. The MCP14628 and MCP14700 feature excellent latch-up immunity, enabling robust applications in the consumer and computing markets, such as digital power conversion, DC-to-DC power supplies, three-phase BLDC motor control and telecom equipment.

The MCP14628 2A synchronous buck power MOSFET driver includes an enhanced light-load efficiency mode that conserves energy when the power supply is not in full use. The dual-input MCP14700 high-speed synchronous MOSFET driver is suitable for controllers that use 3.0V TTL/CMOS logic, and can control the high and low sides independently, which optimizes the timing between the two sides and further maximizes efficiency. Additionally, the MCP14700 driver's timing can be adjusted to a wide range of external MOSFETs, giving designers more flexibility to use different types of MOSFETs in their applications.

Pricing: The MCP14628 and MCP14700 MOSFET drivers cost $1.17 and $1.33 each respectively, in 10,000-unit quantities.
Availability: Production quantities.
