10 PCS TL494 PWM Controller Module Adjustable 5V Frequency 500-100kHz 250mA Control Board For Arduino
Description:
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.
Feature:
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:
1.Desktop PCs;
2.Microwave ovens;
3.Power supplies: AC/DC, isolated, with PFC, > 90 W;
4.Server PSUs;
5. Solar micro-inverters;
6.Washing machines: low-end and high-end;
7.Power supplies: AC/DC, isolated, No PFC, < 90 W;
8.Smoke detectors;
9.Solar power inverters.
