Description

The SG3525 is a versatile PWM controller with an integrated voltage reference and error amplifier, designed to provide precise control over switching regulators and other power circuits. It includes features for dead-time control, oscillator frequency adjustment, and output stage driving.

Features

  • PWM Control: Generates pulse width modulation signals for controlling power delivery.
  • Internal Voltage Reference: Includes a stable 2.5V reference voltage for accurate feedback control.
  • Error Amplifier: Provides an internal error amplifier for adjusting the PWM duty cycle based on feedback.
  • Oscillator: Features a built-in oscillator with adjustable frequency, typically up to 100 kHz, for generating PWM signals.
  • Dead-Time Control: Allows for dead-time control to prevent overlap in switching events, improving efficiency and reducing losses.
  • Output Stage: Equipped with a totem pole output stage capable of driving external power transistors.

Specifications

  • Supply Voltage (Vcc): 7V to 40V
  • Oscillator Frequency: Adjustable up to 100 kHz
  • Output Drive Current: Typically 200 mA (sink/source)
  • Internal Reference Voltage: 2.5V
  • Operating Temperature Range: -40°C to 85°C
  • Package Type: DIP-16 (Dual In-line Package with 16 pins)

Applications

  • Switch-Mode Power Supplies (SMPS): Utilized in designing various types of SMPS, including buck, boost, and flyback converters.
  • Motor Control: Implements PWM control for regulating motor speed and direction.
  • DC-DC Converters: Provides PWM control for converting DC voltages efficiently.
  • Power Inverters: Used in circuits that convert DC to AC power, ensuring stable operation.
  • Battery Chargers: Applied in battery charging circuits for controlled charging current.
