Microchip Technology Inc. announces the MCP14628 and MCP14700 synchronous Buck MOSFET Drivers, which complement market trends toward “green” products by providing maximum efficiency in small packages. With both available in small 8-pin SOIC and 3 x 3 mm DFN packages, the new devices drive two N-Channel MOSFETs arranged in a non-isolated, synchronous Buck converter topology. They 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 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 driver is suited 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.
