SD46520
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.
