Description and Introduction

High Voltage Switching Regulator The MC33363ADW is a high-voltage switching regulator manufactured by Motorola (now part of ON Semiconductor). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- **MOT** (Motorola Semiconductor, now part of ON Semiconductor)  

### **Specifications:**  
1. **Input Voltage Range:**  
   - 8.0V to 40V (operating range)  

2. **Output Voltage:**  
   - Adjustable via external components  

3. **Output Current:**  
   - Up to 1.5A (peak switch current)  

4. **Switching Frequency:**  
   - Fixed at 100 kHz  

5. **Duty Cycle:**  
   - Up to 90%  

6. **Operating Temperature Range:**  
   - -40°C to +85°C  

7. **Package:**  
   - **SOIC-16 (DW)**  

### **Descriptions:**  
- The MC33363ADW is a monolithic high-voltage switching regulator designed for step-down (buck), step-up (boost), and flyback converter applications.  
- It includes an internal temperature-compensated reference, oscillator, high-gain error amplifier, and a high-current output switch.  
- Suitable for automotive, industrial, and consumer electronics applications.  

### **Features:**  
1. **Internal Power Switch:**  
   - NPN Darlington transistor with 1.5A peak current capability.  

2. **Adjustable Output Voltage:**  
   - Configured using external resistors.  

3. **Undervoltage Lockout (UVLO):**  
   - Ensures proper operation by disabling the regulator if input voltage is too low.  

4. **Cycle-by-Cycle Current Limiting:**  
   - Protects the device from overcurrent conditions.  

5. **Thermal Shutdown:**  
   - Prevents damage due to excessive temperature.  

6. **Soft-Start Capability:**  
   - Reduces inrush current during startup.  

7. **Low Standby Current:**  
   - Typically 1.5mA when disabled.  

8. **Wide Input Voltage Range:**  
   - Supports operation from 8V to 40V.  

This information is based on the manufacturer's datasheet for the MC33363ADW.
