AME5284
4A, 300KHz ~ 1.4MHz Synchronous
Rectified Step-Down Converter
n General Description
The AME5284 is a Synchronous Rectified Step-Down
Converter with internal power MOSFETs. It achieves 4A
continous output current over a wide switching frequency
range with excellent load and line regulation.
Current mode operation provides fast transient response
and eases of loop stabilization. Internal soft-start mini-
mizes the inrush supply current at startup. The circuit
protection includes cycle-by cycle current limiting, out-
put short circuit frequency protection and thermal shut-
down.
This device is available in SOP-8/PP package with ex-
posed pad for low thermal resistance.
