Product Description
10pcs TL494 PWM Controller Module Pulse Width Modulation Board DC 5V 250mA
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
Specification:
1.Working voltage: DC 7V-40V
2.Operating frequency 500Hz-100kHz (adjustable R6)
3.Maximum output current: 250mA
4.Output voltage: DC 5V
5.Size: 26 x 23mm
Application:
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
