Description and Introduction

350mA, 16.5V Input, Low-Dropout Linear Regulators The MAX1658ESA+ is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual details about this component:

### **Manufacturer:**  
- **MAX** (Maxim Integrated)

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** 1.25V to 5.5V (adjustable)  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA+)  
- **Regulation Type:** PWM (Pulse-Width Modulation)  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions:**  
The MAX1658ESA+ is a synchronous-rectified, step-down DC-DC converter designed for high-efficiency power conversion in applications requiring a wide input voltage range. It integrates a high-side P-channel MOSFET and a low-side N-channel MOSFET, reducing external component count.  

### **Features:**  
- **High Efficiency:** Up to 96% due to synchronous rectification.  
- **Wide Input Range:** Operates from 4V to 30V.  
- **Adjustable Output:** Output voltage can be set from 1.25V to 5.5V.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection:** Safeguards against fault conditions.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.
