Description and Introduction

PMIC for Microprocessors or DSPs in Portable Equipment The MAX8620YETD is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8620YETD  
- **Package:** TDFN-EP (8-pin, 3x3mm)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (1.8V to 5.5V)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**
The MAX8620YETD is a high-efficiency, low-noise, step-up DC-DC converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and operates from input voltages as low as 0.7V, making it suitable for single-cell alkaline or NiMH/NiCd batteries.  

### **Features:**
- **True Shutdown Mode:** Disconnects the load from the input when disabled.  
- **Low Start-Up Voltage:** Operates down to 0.7V.  
- **Synchronous Rectification:** Improves efficiency and eliminates external Schottky diode.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 25µA (typical).  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Small Footprint:** 3x3mm TDFN package.
