AZ7500C - BCD Semiconductor

AZ7500C Pulse-Width-Modulation Controller

The AZ7500B/C is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control. The AZ7500B/C consists of a reference voltage circuit, two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, and an output control circuit. The prec.
