PULSE-WIDTH-MODULATION CONTROL CIRCUITS
General Description
Features
AZ7500E
The AZ7500E is a voltage mode pulse width modula- · Stable 4.95V Reference Voltage Trimmed to
tion switching regulator control circuit designed pri-
±1.0% Accuracy
marily for power supply control.
· Uncommitted Output TR for 200mA Sink or
Source Current
The AZ7500E consists of a reference voltage circuit, · Single-End or Push-Pull Operation Selected by
two error amplifiers, an on-chip adjustable oscillator, a
Output Control
dead-time control (DTC) comparator, a pulse-steering · Internal Circuitry Prohibits Double Pulse at Either
control flip-flop, and an output control circuit. The pre-
Output
cision of voltage reference (VREF) is improved up to
· Complete PWM Control Circuit with Variable
1% through trimming and this provides a better output
Duty Cycle
voltage regulation. The AZ7500E provides for push- · On-Chip Oscillator With Master or Slave Opera-
pull or single-ended output operation, which can be
tion
selected through the output control.
AZ7500E is the enhanced version of AZ7500B for it
improves REF Pin's reliability comparing with
AZ7500B.
The AZ7500E is available in standard packages of
DIP-16 and SOIC-16.
