The SG3525ADW is a pulse width modulator (PWM) control circuit designed to offer precise control for a wide range of switching power supplies. It features an on-chip 5.1V reference, trimmed to ±1% accuracy, as well as a precision error amplifier with common-mode voltage ranging to ensure high performance. The device offers soft-start functionality with external timing control and built-in undervoltage lockout to prevent operation under low supply conditions.

The SG3525ADW is highly efficient in controlling external transistors, making it ideal for DC-DC converters, inverters, and other power supply designs. It can operate over a frequency range of 100Hz to 400kHz, and its output drivers are capable of sourcing and sinking 200mA continuously with peaks of 400mA. Available in a compact SOIC-16L surface-mount package, it supports ease of design for compact power applications.

Key Features :

  • Package Type: SOIC-16L package, designed for surface mount applications.
  • Wide Operating Voltage: Operates from 8V to 35V, allowing for flexibility in design.
  • Adjustable Oscillator Frequency: Frequency range from 100Hz to 400kHz, programmable with external resistors and capacitors.
  • Built-in 5.1V Reference: The on-chip reference voltage is trimmed to ±1%, ensuring high accuracy and stability.
  • Undervoltage Lockout: Provides reliable protection by preventing operation when supply voltage is too low.
  • High Drive Capability: The output stage can source and sink 200mA, with peak currents up to 400mA, making it suitable for driving external transistors.
