AZ494B PULSE-WIDTH-MODULATION CONTROLLER

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 .
