4-channel switching regulator
BA9710KV
The BA9710KV, a 4-channel switching regulator that uses a pulse width modulation (PWM) system, can drive all channel PNP transistors directly. Channels 2 and 3 can be used for motor control because protection circuits are not built in. 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 and 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 channels 3 and 4, or all channels at once.
FRecommended operating conditions (Ta = 25_C)
