BD9731KV Datasheet (Rohm) - 5-channel switching regulator controller

BD9731KV, 5-channel switching regulator controller

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.
