Fairchild KA7500 - PWM Controller IC (Pack of 5)

  • $11.88


Description:
The KA7500 is used for the control circuit of the pulse-width modulation switching regulator. The KA7500 consists of 5V reference voltage circuit, two error amplifiers, flip flop, an output control circuit, a PWM comparator, a dead-time comparator and an oscillator. This device can be operated in the switching frequency of 1kHz to 300kHz. The precision of voltage reference (VREF) is improved up to u00b11% with trimming. This provides a better output voltage regulation.

Included:

  • 5 x KA7500

This item features:

  • Internal Regulator Provides a Stable 5V Reference Supply Trimmed to 1% Accuracy

  • Uncommitted Output TR for 200mA Sink or Source Current

  • Output Control for Push-Pull or Single-Ended Operation

  • Variable Duty Cycle by Dead-Time Control (Pin 4) Complete PWM Control Circuit

  • On-Chip Oscillator with Master or Slave Operation

  • Internal Circuit Prohibits Double Pulse at Either Output
