DESCRIPTION
The IP1P125 series of pulse width modulator intergrated circuits offers high speed performance optimized for
MOSFET drive. Pin compatible with SG1525A, the IP1P125 features low crossover current through the output transistors
as well as 95% total usable output pulse width up to 500KHz. High speed latched shutdown is included as well as a pre-
cision 5.1 volt rference, error amp, oscillator, latched PWM coparator, totem-pole output drivers, soft-start and undervolt-
age lockout.
