Description and Introduction

24 V Output MOS Chopper Regulator The STK733C is a hybrid IC (integrated circuit) manufactured by Sanyo. It is commonly used in audio amplifier applications. Below are the factual details about the STK733C:

### **Manufacturer:**  
- **Sanyo** (now part of ON Semiconductor after acquisition)  

### **Specifications:**  
- **Type:** Hybrid IC (Thick Film Hybrid)  
- **Function:** Audio Power Amplifier  
- **Output Power:** Typically around 30W (depending on the circuit configuration and supply voltage)  
- **Operating Voltage:** Typically operates at ±25V to ±30V (dual supply)  
- **Package:** SIP (Single In-line Package) with multiple pins  
- **Number of Channels:** 1 (Mono)  

### **Descriptions and Features:**  
- Designed for high-fidelity audio amplification in stereo systems and amplifiers.  
- Contains built-in thermal protection to prevent overheating.  
- Low distortion and noise characteristics for improved audio performance.  
- Requires external components (resistors, capacitors) for proper operation.  
- Commonly used in home audio systems, amplifiers, and vintage stereo equipment.  

For exact electrical characteristics and application circuits, refer to the official datasheet from Sanyo (or ON Semiconductor archives).

Application Scenarios & Design Considerations

24 V Output MOS Chopper Regulator

Alternative Part Number

  • LA7838 --: Sanyo vertical deflection IC in the same application family, commonly used as a substitute in CRT TV/monitor deflection circuits with similar supply and output ratings.
  • TDA8172 --: Widely available vertical deflection output IC with comparable function and pinout, frequently used to replace Sanyo STK-series deflection devices.
  • AN5521 --: Vertical deflection IC with similar voltage and current capability, often cross-referenced for Sanyo STK733C in television chassis repairs.
  • STK730-020 --: Same STK730/733 hybrid regulator family with comparable voltage and current ratings, widely used as a drop-in substitute in CRT power supplies.
  • STR-M6524 --: Similar hybrid voltage regulator module used in TV/monitor power circuits, offering comparable output characteristics and package style.
  • STK734 --: Closely related STK73x series hybrid regulator with similar pinout and ratings, suitable for substitution with minor circuit verification.
