PULSE-WIDTH-MODULATION CONTROL CIRCUITS  
AZ494B/D  
General Description  
Features  
The AZ494B/D is a voltage mode pulse width modula-  
tion switching regulator control circuit designed pri-  
marily for power supply control.  
·
·
·
·
·
·
Stable 4.95V for AZ494B or 5V for AZ494D Ref-  
erence Voltage Trimmed to ±1.5% Accuracy  
Uncommitted Output TR for 200mA Sink or  
Source Current  
Single-End or Push-Pull Operation Selected by  
Output Control  
Internal Circuitry Prohibits Double Pulse at Either  
Output  
Complete PWM Control Circuit with Variable  
Duty Cycle  
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, which can be selected through the  
output control.  
On-Chip Oscillator with Master or Slave Opera-  
tion  
AZ494B has 4.95V and AZ494D has 5V reference  
voltage respectively. The precision of voltage reference  
Applications  
(V ) is improved up to ± 1.5% through trimming  
REF  
and this provides a better output voltage regulation.
