The AP64060QWU-7 from Diodes Incorporated is a Synchronous Buck DC-DC Converter that steps down an input voltage of 4.5 - 40 V to an output voltage of 0.8 - 26 V. It has a switching frequency of 2.2 MHz and an efficiency of up to 82%. This converter fully integrates a 600 mΩ high-side power MOSFET and a 300 mΩ to provide a high-efficiency step-down DC-DC conversion. It uses a peak current mode control algorithm and incorporates a loop compensation network to minimize the external component count, thereby simplifying the converter design. This AEC-Q100 qualified device is optimized to reduce electromagnetic interference (EMI) and utilizes a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency EMI noise.

The AP64060QWU-7 consists of under-voltage lockout (UVLO), output over-voltage protection (OVP), cycle-by-cycle peak current limit, and thermal shutdown to prevent short-circuit-related damages. This RoHS compliant converter is available in a surface-mount package that measures 3 x 2.8 x 1 mm and is ideal for eMeters, FPGA, DSP, ASIC supplies, 5 V, 12 V, and 24 V distributed power bus supplies, white goods, small home appliances, general-purpose point-of-load (POL) devices, and automotive device applications.
