SG3525 pulse width modulation controller is as modified SG3524, more suitable for using MOS as DC/DC converter switching devices, it is a two-stage process model of analog and digital mixed integrated circuit fabrication, excellent performance, required a few peripheral components
1, onboard SG3525A PWM control chip
2, on-board 78M05 regulator chip, providing reliable reference voltage
3, onboard two precision adjustable resistor, R3 to control the duty ratio, R4 control frequency
4, onboard power indicator
5, working voltage: 8 ~ 12V
6, onboard size: 30.8 (mm) x18 (mm)
Characteristics
(1) operating voltage range: 8~35V
(2) 5.1V + 1% trimming reference supply
(3) oscillator for frequency bubble: l00~400kHz
(4) oscillator with external synchronization function
(5) the adjustable dead time
(6) the built-in soft start circuit
(7) with the under voltage lock function
(8) PWM latch function, prohibition of multi pulse
(9) by pulse off
(10) dual output (current): 500mA (peak)
