REGULATING PULSE WIDTH MODULATORS
8-V to 35-V Operation
5.1-V Reference Trimmed to 1%
The UC1525A/1527A series of pulse width modulator
integrated circuits are designed to offer improved
100-Hz to 500-kHz Oscillator Range
performance and lowered external parts count when

supplies. The on-chip +5.1-V reference is trimmed to
1% and the input common-mode range of the error

provides a wide range of dead-time adjustment.
These devices also feature built-in soft-start circuitry
with only an external timing capacitor required. A
shutdown terminal controls both the soft-start circuitry
and the output stages, providing instantaneous turn
off through the PWM latch with pulsed shutdown, as
well as soft-start recycle with longer shutdown
commands.
