Description and Introduction

Programmable, 4A, USB, Current-Limited Switches with Autoreset and Fault Blanking The MAX1562HESA+T is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA)  

### **Descriptions:**  
- The MAX1562HESA+T is designed for low-input voltage applications, making it suitable for battery-powered devices.  
- It integrates a synchronous rectifier for improved efficiency and reduced external component count.  
- The device includes a low-battery detector and a power-OK (POK) output for system monitoring.  

### **Features:**  
- **True Shutdown Mode:** Disconnects the load from the input, reducing leakage current.  
- **Low Quiescent Current:** 20µA (typical) for improved battery life.  
- **Internal Soft-Start:** Prevents inrush current during startup.  
- **Synchronous Rectification:** Enhances efficiency and eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage:** Set via an external resistor divider.
