Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers The MAX773CSD is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX773CSD  
- **Package:** SOIC-8  
- **Input Voltage Range:** 4V to 16V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V (fixed or programmable)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 300kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX773CSD is a step-down (buck) DC-DC converter designed for high-efficiency power conversion.  
- It integrates a power MOSFET switch, reducing external component count.  
- Suitable for battery-powered applications, portable devices, and embedded systems.  
- Features pulse-width modulation (PWM) control for stable output regulation.  

### **Features:**
- **High Efficiency:** Up to 95% efficiency minimizes power loss.  
- **Low Quiescent Current:** Typically 110µA in shutdown mode.  
- **Adjustable/Fixed Output:** Supports both fixed (3.3V or 5V) and adjustable outputs.  
- **Current-Limit Protection:** Built-in protection against overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Low Dropout Operation:** Maintains regulation even with small input-output differentials.
