Description and Introduction

TOPSwitch-FX Family Design Flexible, EcoSmart?, Integrated Off-line Switcher The TOP234P is a member of the TOPSwitch-GX family of integrated switching power supply ICs manufactured by Power Integrations (PI).  

### **Specifications:**  
- **Input Voltage Range:** 85V AC to 265V AC  
- **Output Power:** Up to 29W (depending on configuration)  
- **Switching Frequency:** 132 kHz  
- **Maximum Drain-Source Voltage (V_DS):** 700V  
- **Maximum Drain Current (I_D):** 1.5A  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** TO-220-7C (Through-hole)  

### **Descriptions:**  
The TOP234P is a highly integrated offline switcher IC that combines a high-voltage MOSFET, PWM controller, and protection circuits into a single package. It is designed for use in flyback, forward, and buck-boost converters for applications such as AC-DC power supplies, battery chargers, and LED drivers.  

### **Features:**  
- **Integrated High-Voltage MOSFET:** Reduces external component count.  
- **Frequency Jittering:** Minimizes EMI emissions.  
- **Auto-Restart Protection:** Includes over-temperature, over-voltage, and over-current protection.  
- **Soft-Start:** Reduces inrush current.  
- **Line Under-Voltage Lockout (UVLO):** Ensures stable operation under low input voltage conditions.  
- **EcoSmart® Technology:** Enhances energy efficiency for compliance with global energy standards.  

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

Application Scenarios & Design Considerations

TOPSwitch-FX Family Design Flexible, EcoSmart?, Integrated Off-line Switcher

Alternative Part Number

  • LNK364PN --: Same manufacturer's LinkSwitch-TN family, integrated offline switcher in DIP-8 package with comparable power range; pin-compatible in many low-power designs and a common drop-in replacement for TOP234P.
  • VIPER22A --: Widely available offline PWM switcher in DIP-8 with integrated high-voltage MOSFET, similar power capability and pinout; frequently used as a cross for TOP234P in low-power AC-DC supplies.
  • NCP1014AP065G --: Self-supplied monolithic offline switcher in DIP-8 with integrated MOSFET and current-mode control, offering comparable output power and a similar application footprint to the TOP234P.
  • TOP244PN --: Same TO-220-7 package and TOPSwitch-GX family with higher power rating, so it is a drop-in upgrade with margin.
  • TOP243PN --: Same TOPSwitch-GX family and pinout in TO-220-7, slightly higher power capability than TOP234P.
  • TOP234GN --: Same TOPSwitch-GX family and electrical rating but in SMD-8 package; suitable if board layout allows surface-mount adaptation.
