Overview

Regulator ICs 4-channel switching regulator controller BA9737KV The BA9737KV is a 4-channel controller that includes all of the circuits required to construct a switching regulator.
The circuits on the chip include a triangular-wave oscillator, a reference voltage circuit, an error amplifier, a PWM comparator, a pseudo-totem-pole driver, and a short-circuit protection circuit.
FApplications Camcoders and digital still cameras etc.
FFeatures 1) The totem-pole driver can directly drive power transistors, and the on current can be set to the rating current using an external resistor.
For the off current, the peak current can be set using an external capacitor.
2) Output cutoff circuit (timer l...
