Uncommitted Output TR for 200mA Source Curre nt or Si nk

Push-Pull or Single-E nded Operation Output Control

Dead-Time Control Variable Duty Cycle (Pin 4) pWm Control Circuit in Its Entiret

Oscillator on-chip with Master or Slave Operation

Double Pulse at Either Output Is Prohibited by Internal Circuit

KA7500C Applications

The switching frequency of KA7500C ranges from 1kHz to 300kHz. Trimming improves the precision of the voltage reference network (Vref) by up to 1%. This results in more consistent output voltage control.
