AZ494
VOLTAGE MODE DUAL OUTPUT PWM CONTROLLER
Description
The DIODES™ AZ494 is a voltage mode pulse width modulation switching
regulator control circuit designed primarily for power supply control.
The AZ494 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 (VREF) is improved up to ±1% through trimming and this provides a better output voltage regulation.
The AZ494 provides for push-pull or single-ended output operation, which can be selected through the output co...
