General Description

s 414 Regulator ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 6.0V, fosc = 0.45MHz, STB, STB1 to STB4 = 5V) BA9737KV 415 Regulator ICs FOperation notes (1) Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance as small as possible, and use inductors and capacitors to keep ripple to a minimum.

(2) Great care has been paid to the quality of this component.

However, if the absolute maximum ratings for temperature and applied voltage are exceeded, the IC may be destroyed.

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.

Key Features

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 latch type) for overload protection. 3) Channels 2 and 3 are supplied using the internal reference voltage, and use a positive voltage only. Channels 1 and 4 are general-purpose channels, and all inputs are externally available. 4) Channels can b.
