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

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

The TL494 device integrates all necessary functions for constructing a pulse-width-modulation (PWM) control circuit within a single chip. Primarily aimed at controlling power supplies, this device provides the versatility to customize the power-supply control circuitry for particular applications.

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
