4-channel switching regulator
The BA9707KV, a 4-channel switching regulator that uses a pulse width modulation (PWM) system, can drive all channel PNP transistors directly.
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.
Applications
VCRs and other portable equipment
