The SG3525AN from Microchip Technology is a pulse width modulator control circuit designed for efficient control of switching power supplies. It offers improved performance with a reduced external parts count. The integrated 5.1V reference is trimmed to ±1%, and the error amplifier accommodates a wide input common-mode voltage range, eliminating the need for external resistors.
Key features include an adjustable deadtime control, built-in soft-start circuitry, and under-voltage lockout. The device operates over a voltage range of 8.0V to 35V and supports an oscillator frequency range from 100 Hz to 400 kHz. It provides dual source/sink outputs capable of 400 mA peak current.
This controller is suitable for step-up/step-down applications and features a push-pull topology. It is available in a 16-PDIP package and supports through-hole mounting. The operating temperature range is 0°C to 70°C (TA).
The SG3525AN includes control features such as enable, frequency control, and soft start. Its latching PWM prevents multiple pulses, and it offers pulse-by-pulse shutdown for enhanced protection. The device also features separate oscillator sync for slaving multiple units or synchronizing to an external clock.
