Regulator ICs
4-channel switching regulator
BA9710KV
The BA9710KV, a 4-channel switching regulator that uses a pulse width modulation (PWM) system, can drive all channel
PNP transistors directly. Channels 2 and 3 can be used for motor control because protection circuits are not built in.

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 and
OFF currents can be set independently.
3) Triangular waves can be externally synchronized.
4) Pins allow ON / OFF control of channels 3 and 4, or
all channels at once.
