Regulator ICs
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. FApplications VCRs and other portable equipment FFeatures 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. FAbsolute maximum ratings (Ta = 25_C)
3) Triangular waves can be externally synchronized. 4) Pins allow ON / OFF control of channel 4 only, or all channels at once.
FRemended operating conditions (Ta = 25_C)
