Description and Introduction

SYNCHRONOUS RECTIFICATION DC/DC CONVERTER PROGRAMMABLE INTEGRATED CONTROLLER The MC33470DW is a voltage regulator manufactured by Motorola (now part of ON Semiconductor).  

### **Specifications:**  
- **Type:** Low Dropout (LDO) Voltage Regulator  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 500 mA  
- **Dropout Voltage:** Typically 0.5V at full load  
- **Input Voltage Range:** Up to 16V  
- **Package:** SOIC-16 (DW suffix indicates the package type)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Overcurrent protection  
  - Thermal shutdown  
  - Adjustable output voltage  
  - Low quiescent current  

### **Descriptions and Features:**  
The MC33470DW is designed for applications requiring a stable, low-dropout voltage supply. It is suitable for battery-powered systems, portable electronics, and automotive applications due to its wide input voltage range and robust protection features. The adjustable output allows flexibility in design, while built-in safeguards ensure reliability under varying load conditions.  

For exact electrical characteristics, refer to the official datasheet from ON Semiconductor (formerly Motorola).

Application Scenarios & Design Considerations

SYNCHRONOUS RECTIFICATION DC/DC CONVERTER PROGRAMMABLE INTEGRATED CONTROLLER

Alternative Part Number

  • LM3478MM --: Widely available low-side N-channel MOSFET controller in an SOIC-8 package, functionally similar to the MC33470DW for DC-DC conversion applications.
  • UC3843BD1 --: Industry-standard current-mode PWM controller in SOIC-8, commonly used as a drop-in style replacement for older Motorola PWM controller designs.
  • SG3524BD --: Classic PWM regulator/controller IC in SOIC-16, suitable for power supply designs where the MC33470DW was used, with broad second-source availability.
