Regulators

Inverting Switching Regulator Controller

BD9718G

The BD9718G is a high performance fixed frequency power switching regulator. This regulator was specifically designed

to be incorporated for step-down and voltage inverting functions with a minimum number of external components.

Applications

Pre-amplifier bias supply for hard disk drive (HDD),

designs or other voltage inverter requirements.

Features

1) High-accuracy output voltage detection. (Vs=

−5.00±1%)

2) High switching frequency (900kHz typ.)

3) Built-in soft start function. (No external components required.)

4) Timer latch type short protection function. (No external components

required.)

5) Ultra small package: SMP5C2
