AP494  
Voltage Mode PWM Controller  
„ Features  
„ Description  
- Complete PWM Power Control Circuitry  
- Uncommitted Outputs for 200-mA Sink or Source  
Current  
The AP494 incorporates on a single monolithic chip  
all the functions required in the construction of a  
pulse-width-modulation control circuit. Designed  
primarily for power supply control, this device offers  
the systems engineer the flexibility to tailor the

- Variable Dead Time Provides Control Over Total  
Range  
The AP494 contains two error amplifiers, one  
adjustable on-chip oscillator, a dead-time control  
(DTC) comparator, a pulse-steering control flip-flop,  
a 5-V, 3%-precision regulator, and output-control  
circuits.

- Circuit Architecture allows Easy Synchronization  
The error amplifiers exhibit

voltage range from –0.3V to VCC –2V. The  
dead-time control comparator has a fixed offset that  
provides approximately 5% dead time. The  
on-chipped oscillator may be bypassed in two ways.  
One is to terminate RT to the reference output  
and the other one is to provide a sawtooth input to  
CT, or it may drive the common circuits in  
synchronous multiple-rail power supplies.

capability. The AP494 provides for push-pull or  
single-ended output operation, which may be  
selected through the output-control function. The  
architecture of this device prohibits the possibility of  
either output being pulsed twice during push-pull  
operation.
