Description and Introduction

SWITCH MODE POWER SUPPLY CONTROLLER The TEA2260 is a switching regulator controller manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Type:** Switching Regulator Controller  
- **Topology:** Flyback, Forward  
- **Input Voltage Range:** Up to 40V  
- **Output Voltage:** Adjustable (depends on external components)  
- **Switching Frequency:** Adjustable (typically up to 500 kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** DIP-16, SO-16  

### **Descriptions:**  
The TEA2260 is a monolithic integrated circuit designed for offline and DC-DC converter applications. It provides control for flyback and forward converters, offering features like soft-start, overcurrent protection, and adjustable frequency operation.  

### **Features:**  
- **Soft-start function** for controlled startup  
- **Adjustable oscillator frequency**  
- **Overcurrent protection** with latch or auto-restart mode  
- **Undervoltage lockout (UVLO)** for safe operation  
- **High-current totem-pole output** for driving power MOSFETs  
- **Low standby power consumption**  

For exact electrical characteristics and application details, refer to the official STMicroelectronics datasheet.

Application Scenarios & Design Considerations

SWITCH MODE POWER SUPPLY CONTROLLER

Alternative Part Number

  • UC3842 --: Industry-standard current-mode PWM controller widely used in offline SMPS, functionally similar to the TEA2260 control loop and easy to source.
  • SG6848 --: Green-mode PWM controller for flyback converters, comparable application role and pin-compatible design approach for low-power adapters.
  • NCP1200 --: Self-supplied current-mode PWM controller for isolated flyback supplies, offering similar regulation function with integrated high-voltage startup.
