Regulator ICs

3-channel switching regulator

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
