SG3525AP013TR ST DC-DC Controllers

The SG3525AP013TR is a high-performance pulse width modulator IC from STMicroelectronics designed for switch-mode power supply applications, in a 16-pin SOIC package . For selection, verify supply voltage from 8V to 35V, confirm oscillator frequency range from 100Hz to 500kHz (adjustable), note maximum duty cycle of 49%, reference voltage of 5.1V with ±1% accuracy, dual totem-pole output drivers capable of sourcing/sinking 200mA, and operating temperature from 0°C to +70°C . Features include internal soft-start requiring only external timing capacitor, adjustable dead-time control via single resistor, oscillator synchronization input for multiple-unit lock, under-voltage lockout with hysteresis (approx 500mV) for jitter-free operation, and shutdown control for PWM latch and soft-start discharge . Applications include off-line SMPS, DC-DC converters, uninterruptible power supplies (UPS), battery chargers, and industrial power control systems requiring high-performance voltage-mode PWM control.
