IP1P125 IP3P125
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 precision 5.1 volt rference, error amp, oscillator, latched PWM coparator, totem-pole output drivers, soft-start and undervoltage lockout.
