FA5304AP(S)/FA5305AP(S)

s

Description

The FA5304AP(S) and FA5305AP(S) are bipolar ICs for

switching power supply control and can directly drive a power

MOSFET. These ICs contain many functions in a small 8-pin

package. With these ICs, a high-performance power supply

can be created compactly because not many external

components are needed.
