DESCRIPTION
The UC3578 is a PWM controller with an integrated high side floating gate driver. It is used in buck step down converters and regulates a positive output voltage. Intended to be used in a distributed power system, the IC allows operation from 14V to 72V input voltage which range includes the prevalent telecomm bus voltages. The output duty cycle of the UC3578 can vary between 0% and 90% for operation over the wide input voltage and load conditions.

FEATURES
• Provides Simple Single Inductor Buck PWM Step-Down Voltage Regulation
• Drives External High Side NMOS Switch
• 14V to 72V Input Voltage Operating Range
• Contains 100kHz Internal Oscillator, 2V Reference and UVLO
• Soft Start on Power Up
• Overcurrent Shutdown Followed by Soft Start
