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

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.

Features:

1.Complete PWM power-control circuitry
2.Uncommitted outputs for 200-mA sink or source current
3.Output control selects single-ended or push-pull operation
4.Internal circuitry prohibits double pulse at either output
5.Variable dead time provides control over total range
6.Internal regulator provides a stable 5-V reference supply with 5% tolerance
7.Circuit architecture allows easy synchronization

Applications:

Desktop PCs, Microwave ovens, Power supplies: AC/DC, isolated, with PFC, > 90 W, Server PSUs, Solar micro-inverters, Washing machines: low-end and high-end, Power supplies: AC/DC, isolated, No PFC, < 90 W, Smoke detectors, Solar power inverters

Package include:

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