DP2545 PWM Controller IC for SMPS Power Supply - DIP-7 Package

The DP2545 High Precision CC/CV Primary-Side PWM Power Switch is a high-performance offline controller designed for low power AC/DC chargers and adapters. Featuring Primary Side Regulation (PSR) technology, it eliminates the need for optocoupler and TL431 components, reducing system cost and improving reliability. With integrated high-precision Constant Voltage (CV) and Constant Current (CC) control, the DP2545 ensures stable output performance for battery chargers, small power adapters, and auxiliary power supplies. Its multi-mode PWM/PFM operation enhances efficiency while achieving less than 75mW standby power consumption.DP2545 DatasheetFeatures:±5% High Precision CV/CC Regulation – Stable constant voltage and current control at universal AC input.Primary Side Regulation (PSR) – No need for optocoupler or TL431.Multi-Mode PWM/PFM Operation – High efficiency across load conditions.Low Standby Power – Less than 75mW standby consumption.Programmable Output Settings – Adjustable CC point via external sense resistor.Built-in Protection Functions – Cycle-by-cycle current limiting, UVLO, VDD OVP, OTP.Audio Noise Free Operation – Suitable for charger and adapter applications.650V Built-in Power MOSFET – High voltage reliability.This IC is widely used in SMPS drives and power supply solutions for low power AC/DC applications, making it ideal for charger and adapter circuit designs.Specifications:Model: DP2545Package: DIP7Drain-Source Breakdown Voltage: 650VVDD Operating Voltage: 11V – 27VUVLO Start Threshold: 15V – 17.5VVDD OVP Threshold: 28V – 32VCurrent Limiting Threshold: 500mV (typ.)Thermal Shutdown: 165°C (typ.)Operating Temperature: -40°C to 85°CApplications:Cell Phone ChargersDigital Camera ChargersSmall Power AdaptersAuxiliary Power Supplies (PC, TV, etc.)Linear Regulator / RCC ReplacementPackage Includes:1 × DP2545 CC/CV Primary Side PWM Controller IC - DIP7 Package
