Data Sheet PULSE-WIDTH-MODULATION CONTROL CIRCUITS General Description
The AZ494B, D is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control. The AZ494B, D 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 AZ494B, D is capable for push-pull or single-ended output operation, whic
