Datasheet Summary
400KHZ 2A STEP-DOWN DC-DC CONVERTER
DESCRIPTION
The SD46520 is a step-down PWM control converter with a built-in internal power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. It provides cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the current is only 23μA.
