The BA9708K is a 3-channel switching regulator that uses a pulse width modulation (PWM) system and can directly drive all channel PNP transistors.
The BA9708K is a 3‑channel switching regulator that uses a pulse‑width‑modulation (PWM) system and can directly drive PNP transistors for each channel. It is intended for use in VCRs and other portable equipment.\n\nKey features include a reference voltage precision of ±1%, push‑pull (totem‑pole) output stages, external synchronization of triangular waveforms, and pins that allow ON/OFF control of channel 3 alone or all channels simultaneously. The datasheet provides block diagrams, pin descriptions, electrical characteristics (with VCC = 6 V and operating temperature 25 °C), reference data, characteristic curves, and mechanical dimensions.
| Reference voltage precision | ± 1% |
|---|---|
| Output stage method | push‑pull (totem‑pole) |
| Synchronization capability | Triangular waves can be externally synchronized |
| Channel ON/OFF control | Pins allow ON/OFF control of channel 3 only, or all channels at once |
It is intended for VCRs and other portable equipment.
The device has three channels, each with independent ON/OFF control, and pins allow control of channel 3 alone or all channels together.
The reference voltage precision is ± 1 %.
