SG3525 PWM Controller IC – Voltage Mode, 8–35V Input, Dual Output, DIP-16 Package

The SG3525 is a high-performance pulse-width modulation (PWM) controller IC designed for switch-mode power supplies and DC-DC converters. It features voltage mode control, built-in soft-start, shutdown capability, and the ability to drive push-pull, half-bridge, or full-bridge topologies. Its dual totem-pole outputs with adjustable dead time make it ideal for power conversion systems such as inverters, UPS systems, battery chargers, and solar charge controllers.

Key Features:

• Voltage-mode PWM controller with dual output capability
• Wide operating voltage range: 8 V to 35 V
• Precision 5.1V internal voltage reference
• Soft-start, shutdown, and under-voltage lockout features
• Adjustable oscillator frequency with external RC
• Dual totem-pole output drivers for push-pull or full-bridge applications
