SN7500x/P
Pulse Width Modulation
Description
The SN7500 is a monolithic integrated circuit which includes all the necessary
building blocks for the design of pulse width modulate(PWM) switching power supplies,
including push-pull, bridge and series configuration. The precision of voltage reference is
improved up to ±1%/±2% through trimming and this provides a better output voltage
regulation. The device can operate at switching frequencies between 1KHz and 300KHz and
output voltage up to 36V.
The SN7500 is specified over an operating temperature range of -40~+85.
Features
Package Type
Internal Regulator Provides a Stable 5V
