TL494 PWM CONTROLLER MODULE

The TL494 device incorporates all the functions required in the construction of a pulse-width- modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application.

• • Complete PWM power-control circuitry
  • Uncommitted outputs for 200-mA sink or source current
  • Output control selects single-ended or push-pull operation
  • Internal circuitry prohibits double pulse at either output
  • Variable dead time provides control over total range
  • Internal regulator provides a stable 5-V reference supply with 5% tolerance
  • Circuit architecture allows easy synchronization
  • PWM output frequency in the range 500Hz-100KHz can be adjustable, maximum duty cycle to 96%.
  • Output drive capability, signal stability;
  • Maximum output current: 250mA;
  • Output voltage: DC5V
  • Maximum power consumption: 1000mW;
  • Working ambient temperature: 0-70 ℃
  • Positioning hole: 2.7mm diameter(M2.5)

Package Includes:

• • 1 x TL494 PWM Controller Module Adjustable 5V Frequency 500-100kHz 250mA
