General Description
The AZ7500B/C is a voltage mode pulse width modu-
lation switching regulator control circuit designed pri-
marily for power supply control.
The AZ7500B/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. The pre-
cision of voltage reference (V
REF
) is improved up to
±
1% through trimming and this provides a better output
voltage regulation. The AZ7500B/C provides for push-
pull or single-ended output operation, which can be
selected through the output control.
The difference between AZ7500B and AZ7500C is that
they have 4.95V and 5V reference voltage respectively.
The AZ7500B/C is available in standard packages of
DIP-16 and SOIC-16.
