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.
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.
