Description and Introduction

Coded locking circuit for security systems The TEA5500T is manufactured by Philips (now NXP Semiconductors).  

**Specifications:**  
- **Type:** Switched Mode Power Supply (SMPS) controller IC  
- **Package:** DIP16 (Dual In-line Package)  
- **Input Voltage Range:** Typically operates with a mains voltage input (90-270V AC)  
- **Output Power:** Designed for low to medium power applications  
- **Switching Frequency:** Adjustable, typically in the range of 20-100 kHz  
- **Protection Features:** Overvoltage protection, overcurrent protection, and thermal shutdown  

**Descriptions:**  
The TEA5500T is an integrated SMPS controller used in power supply circuits for TVs, monitors, and other electronic devices. It provides efficient power conversion with built-in protection mechanisms.  

**Features:**  
- Internal startup circuit  
- Soft-start function  
- Adjustable oscillator frequency  
- Low standby power consumption  
- High integration reduces external component count

Alternative Part Number

  • UC3842AN --: Industry-standard current-mode PWM controller in a DIP-8 package, widely used as a functional substitute for SMPS control ICs like the TEA5500T.
  • SG3524N --: Classic PWM switching regulator controller in DIP-16, offering comparable regulation and drive functions for power supply designs.
  • TL494CN --: Versatile fixed-frequency PWM control IC in DIP-16, commonly used as a replacement in switch-mode power supply control applications.
  • UBA2021T --: NXP (formerly Philips) CFL ballast controller in the same application family, often used as a direct functional substitute for TEA5500T in lighting ballast designs.
  • IRS2530D --: Integrated dimmable fluorescent ballast control IC with comparable functionality and drive capability, suitable as a cross-vendor replacement.
  • L6574 --: CFL/TL ballast controller with oscillator and half-bridge driver, offering similar control functions for ballast applications.
