4-channel switching regulator

BA9707KV

The BA9707KV, a 4-channel switching regulator that uses a pulse width modulation (PWM) system, can drive all channel

PNP transistors directly.

Applications

VCRs and other portable equipment

Features

1) Reference voltage precision is ± 1%.

2) Output stages are based on the push-pull method

(resembling the totem-pole method), and ON/OFF

currents can be set independently.

3) Triangular waves can be externally synchronized.

4) Pins allow ON/OFF control of channel 4 only, or all

channels at once.

Absolute maximum ratings (Ta = 25C)

Recommended operating conditions (Ta = 25C)
