Description and Introduction

GREEN MODE PWM CONTROLLER The LD7552BN is a low-power, current-mode PWM controller IC designed for offline power supplies. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Leadtrend Technology Corp.

### **Key Specifications:**  
- **Input Voltage Range:** Up to 30V (for VCC)  
- **Operating Frequency:** Adjustable (typically 65kHz)  
- **Start-up Current:** < 30µA  
- **Operating Current:** < 3mA  
- **Output Drive Current:** ±500mA (for driving power MOSFETs)  
- **Protection Features:** Over-voltage protection (OVP), over-load protection (OLP), over-temperature protection (OTP)  

### **Descriptions:**  
- The LD7552BN is a cost-effective, energy-efficient PWM controller used in flyback converters for AC/DC power supplies.  
- It operates in current-mode control for improved transient response and cycle-by-cycle current limiting.  
- Suitable for applications like adapters, LED drivers, and auxiliary power supplies.  

### **Features:**  
- **Green Mode Operation:** Reduces power consumption in standby mode.  
- **Built-in Soft Start:** Prevents inrush current during startup.  
- **Frequency Jittering:** Reduces EMI noise.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  
- **Low External Component Count:** Simplifies circuit design.  

For exact electrical characteristics, refer to the official datasheet from Leadtrend Technology.
