Diodes Incorporated AP64060 Synchronous Buck Converter

Diodes Incorporated AP64060 Synchronous Buck Converter is designed for Electromagnetic Interference (EMI) reduction and is available in a TSOT26 package. The AP64060 converter integrates a 600mΩ high-side power MOSFET and a 300mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. This device features a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off. The AP64060 also features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%. Typical applications include 5V, 12V, and 24V distributed power bus supplies, automotive, white goods, small home appliances, FPGA, DSP, ASIC supplies, and general-purpose point of load.
