(2) 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.

Overview

Regulator ICs 6-channel switching regulator controller BA9736KV The BA9736KV is a 6-channel controller that includes all of the circuits required to construct a switching regulator.

The circuits on the chip include a triangular-wave generator, a reference voltage circuit, an error amplifier, a PWM comparator, a pseudo-totem-pole driver, and a variety of protection circuits.

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. 2) Miss-operation prevention circuit for low-voltage input. 3) Output cutoff circuit (timer latch type) for overload protection. 4) Channels 1 and 4 employ FETs, and have totem-pole drivers that rectify synchronously with a chopper. The duty offset of the chopper can be adjusted externally. FAbsolute maximum ratings (Ta = 25_C) 5) For channel control, by.
