Product Overview

AP64501SP-13 is a synchronous buck converter. The device fully integrates a 45mohm high-side power MOSFET and a 20mohm low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The device is easily used by minimizing the external component count due to its adoption of peak current mode control. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency radiated EMI noise caused by MOSFET switching. The AP64501 also features frequency spread spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. Applications include 5V, 12V, and 24V distributed power bus supplies, power tools and laser printers, white goods and small home appliances, home audio, network systems, consumer electronics, general-purpose point of load.
  • Up to 85% efficiency at 5mA light load
  • Proprietary gate driver design for best EMI reduction
  • Low-dropout (LDO) mode, precision enable threshold to adjust UVLO
  • Undervoltage lockout (UVLO), output overvoltage protection (OVP)
  • Cycle-by-cycle peak current limit, thermal shutdown
  • Supply voltage range from 3.8 to 40V
  • Output voltage is 39V max at TA=+25°C
  • Shutdown supply current is 1μA typ at VEN=0V, TJ=+25°C, VIN=12V
  • Operating ambient temperature range from -40 to 85°C
  • SO-8EP package
