Description and Introduction

GreenChip SMPS control IC The TEA1533P is a power supply controller IC manufactured by Philips (now NXP Semiconductors). Here are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** PHILIPS (NXP Semiconductors)  
- **Type:** Switched-Mode Power Supply (SMPS) Controller  
- **Package:** DIP-8 (Dual In-line Package)  
- **Operating Voltage Range:** 8V to 20V (VCC)  
- **Maximum Switching Frequency:** Up to 250 kHz  
- **Standby Power Consumption:** < 100 mW  
- **Protection Features:** Overvoltage, Overcurrent, Overtemperature, and Undervoltage Lockout (UVLO)  

### **Descriptions:**
- The TEA1533P is a cost-effective, low-power SMPS controller designed for flyback converters in offline power supplies.  
- It operates in quasi-resonant mode for improved efficiency and reduced EMI.  
- Suitable for applications like adapters, standby power supplies, and auxiliary power sources.  

### **Features:**
- **High Efficiency:** Quasi-resonant operation reduces switching losses.  
- **Low Standby Power:** Supports energy-saving modes.  
- **Integrated Protections:**  
  - Overvoltage Protection (OVP)  
  - Overcurrent Protection (OCP)  
  - Overtemperature Protection (OTP)  
  - Undervoltage Lockout (UVLO)  
- **Frequency Jittering:** Reduces EMI interference.  
- **Soft Start:** Prevents inrush current at startup.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

GreenChip SMPS control IC

Alternative Part Number

  • NCP1200P60 --: Current-mode PWM controller in DIP-8 with similar offline SMPS function; widely available and often used where TEA1533 was applied.
  • UC3842AN --: Classic current-mode PWM controller in DIP-8, well documented and broadly cross-referenced for low-power flyback supplies.
  • SG6848 --: Green-mode PWM controller for offline flyback adapters, comparable function and package to the TEA1533P.
