KA7500C Description
The KA7500C is utilized in the pulse-width modulation switching regulator's control circuit. A 5V reference voltage circuit, two error amplifiers, a flip flop, an output control circuit, a PWM comparator, a dead-time comparator, and an oscillator are all included in the KA7500C.
KA7500C Features
Internal Regulator Maintains a Stable 5V Reference Supply Trimmed to 1% Accuracy
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.
