BA9708

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 operating conditions (Ta = 25_C) 295 Regulator ICs FBlock diagram BA9708K 296 Regulator ICs FPin descriptions BA9708K 297 Regulator ICs BA9708K FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 6V) 298 Regulator ICs BA9708K 299 Regulator ICs FReference data (unless otherwise noted, Ta = 25_C and VCC = 6V) BA9708K FElectrical characteristic curves FExternal dimensions (Units: mm) 300
