AZ7500BP

IC REG CTRLR BUCK PWM 16DIP

General Description

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 precision of voltage reference V

REF is improved up to ±1% through trimming and this provides a better output voltage regulation. The AZ7500B/C provides for push pull or single-ended output operation, which can be

selected through the output control.
