TL494 Pulse-Width-Modulation Control IC

The TL494IN is a PWM Control Circuit 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.

Features :

• Complete PWM power-control circuitry
• Uncommitted outputs for 200mA 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 5V reference supply with 5% tolerance
• Circuit architecture allows easy synchronization

Applications :

• Computers & Computer Peripherals, Microwave, Power Management, Consumer Electronics, Communications & Networking
