BA9708K

 Reference voltage precision is ± 1%.
 Output stages are based on the push-pull method (resembling the totem-pole method), and ON / OFF currents can be set independently.
 Triangular waves can be externally synchronized.
 Pins allow ON / OFF control of channel 3 only, or all channels at once.

The BA9708K, a 3-channel switching regulator that uses a pulse width modulation (PWM) system, can drive all channel PNP transistors directly.
