Function : PULSE-WIDTH-MODULATION CONTROL CIRCUITS
Maker : BCD Semiconductor
The AZ494A/C is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control. The AZ494A/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.
