BD9731KV - 5-channel switching regulator controller

General Description

BD9731KV is a PWM switching regulator controller IC.

The 5-channel (4 channel for step-up, and 1 channel for step-down) switching regulator controllers are integrated into a VQFP48 package.

This IC can operate both Bipolar and MOS transistor.

Key Features

  • 1) Can operate both external transistors of Bipolar and MOS. (Base current can be set by resistance. ) 2) Built-in output shutdown circuit (Timer latch) when overloaded. 3) Channel 1, and 5 can externally set the reference voltage. 4) Channel 1, 4, and 5 can control independently ON/OFF. 5) All channels have dead time control.
