BA9708K
The BA9708K, a 3-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 3 only, or all channels at once.
FRecommended operating conditions (Ta = 25_C)
