Description and Introduction

2.1MHz, High-Voltage, 1A Mini-Buck Converter The MAX16903RA33/V+TCE is a voltage regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** 300mV (typical at 250mA)  
- **Quiescent Current:** 30µA (typical)  
- **Switching Frequency:** 2.2MHz (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin TDFN (3mm x 3mm)  

### **Descriptions:**  
- The MAX16903RA33/V+TCE is a high-efficiency, low-quiescent-current step-down DC-DC converter.  
- It is designed for automotive and industrial applications requiring a stable 3.3V supply from a wide input voltage range.  
- The device integrates a high-side MOSFET and features a fixed-frequency PWM control scheme.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 40V):** Suitable for automotive battery systems.  
- **Low Quiescent Current (30µA):** Enhances efficiency in standby mode.  
- **High Efficiency (Up to 90%):** Optimized for power-sensitive applications.  
- **Integrated MOSFET:** Reduces external component count.  
- **Fixed 2.2MHz Switching Frequency:** Minimizes EMI and allows for small external components.  
- **Thermal Shutdown and Overcurrent Protection:** Ensures safe operation.  
- **AEC-Q100 Qualified:** Meets automotive reliability standards.  

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