From Makers Electronics's description

SG3525A PWM Controller 500mA SMD IC The SG3525A is a versatile Pulse Width Modulation (PWM) controller designed to provide efficient power regulation in a variety of applications. This integrated circuit is specifically used in the design of switching power supplies and is capable of handling both low and high-frequency operations. It provides a stable voltage reference and features a comprehensive internal circuit for efficient regulation. This PWM controller is built to operate with minimal external components, which simplifies circuit design. It includes an internal voltage reference, an error amplifier, and a duty cycle control mechanism. It’s also supports synchronization with external clocks and allows for flexibility in frequency adjustment. Its ability to work in master-slave mode and its versatile dead-time control make it adaptable for various switching configurations. It’s performance is further enhanced by its soft-start function, which helps in minimizing inrush current during startup. Additionally, the under-voltage lockout (UVLO) feature protects the controller in the event of insufficient voltage supply. Its output stage supports both bipolar transistors and field-effect transistors (FETs), making it ideal for a broad range of power management solutions. Features: High-precision 5.1V reference voltage. Wide frequency range (0.1 Hz to 400 kHz). Soft-start and shutdown features. Under-voltage lockout (UVLO) for protection. Sync input for frequency synchronization. Adjustable dead-time control. Low output voltage distortion. Specifications: Specification Value VCC Supply Voltage: 8.0V to 35V VC Voltage: 4.5V to 35V Output Current: ±100mA (normal), ±400mA (peak) Oscillator Frequency: 0.1Hz to 400 kHz Reference Voltage: 5.0V ± 1% External Timing Resistor: 2kΩ to 150kΩ Soft-start Current: 50µA Shutdown Current: 50µA Power Dissipation: 1000 mW Operating Temp Range: 0°C to +70°C Pinout Diagram: Footprint: Applications: Power Supply Regulation. DC-DC Converters. Voltage Regulators. Switching Power Supply. Inverter Circuits. Package Contents: 1x SG3525A PWM Controller 500mA SMD IC. Datasheet
