TDA4601 is a control IC for switched-mode power supplies (SMPS) manufactured by STMicroelectronics.

The TDA4601 is a control IC for switched-mode power supplies (SMPS) manufactured by STMicroelectronics.

Specifications:

  • Supply Voltage (VCC): 8.5V to 12V
  • Operating Frequency: Adjustable via external components
  • Output Drive Current: Up to 1.2A (peak)
  • Start-Up Current: Typically 0.5mA
  • Standby Power Consumption: Low (suitable for energy-efficient designs)
  • Protection Features: Overvoltage, undervoltage, and overcurrent protection
  • Package: DIP-8 or SO-8

Descriptions:

The TDA4601 is designed to control power MOSFETs or IGBTs in flyback or forward converter topologies. It provides all necessary functions for SMPS, including soft-start, pulse-width modulation (PWM), and protection mechanisms.

Features:

  • Soft-Start Function: Reduces inrush current during startup
  • PWM Control: Adjustable duty cycle for efficient power regulation
  • Overvoltage Protection (OVP): Monitors VCC to prevent damage
  • Undervoltage Lockout (UVLO): Ensures proper operation within voltage range
  • Current Limiting: Protects against excessive load conditions
  • Frequency Jittering: Reduces EMI emissions
  • Thermal Shutdown: Prevents overheating

This IC is commonly used in power supplies for TVs, monitors, and other electronic devices requiring efficient power conversion.
