ATL494 PWM Controller Module Adjustable 5V Frequency 500-100kHz 250mA
BSG3525 PWM Controller Module Adjustable Frequency 200HZ-100KHZ 8V-12V Adjustable Duty Ratio Waveform Generator Board

TL494 module 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.

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

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


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

SG3525 module Description:
1. onboard SG3525A PWM control chip
2. on-board 78M05 regulator chip, providing a reliable reference voltage
3. onboard two precision adjustable resistors, R3 controls the duty cycle, R4 control frequency
4. on-board power indicator
5. the working voltage: 8 ~ 12V
6. Frequency Range  100HZ-100KHZ adjustable
7. Duty Cycle :0 - 100% adjustable
8. voltage : 5v
9. board size: 30.8 (mm) x18 (mm)
