Description and Introduction

µPMIC for Microprocessors or DSPs in Portable Equipment The **MAX8620YETD+** is a power management IC (PMIC) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX8620YETD+  
- **Package:** 14-TDFN (3x3mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 600mA (buck regulator)  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Number of Outputs:** 1 (Buck Regulator)  
- **Control Interface:** Enable Pin (EN)  

### **Descriptions:**
The **MAX8620YETD+** is a high-efficiency, step-down (buck) DC-DC converter designed for portable and low-power applications. It integrates a synchronous rectifier to minimize external components and improve efficiency. The device operates at a fixed 1MHz switching frequency, making it suitable for noise-sensitive applications.

### **Features:**
- **High Efficiency (up to 95%)** – Reduces power loss in battery-operated devices.  
- **Low Quiescent Current (30µA typical)** – Extends battery life.  
- **Synchronous Rectification** – Eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage** – Set via external resistors.  
- **1MHz Fixed Switching Frequency** – Minimizes inductor size and reduces EMI.  
- **Thermal Shutdown & Overcurrent Protection** – Enhances reliability.  
- **Small Footprint (3x3mm TDFN)** – Ideal for space-constrained designs.  
- **Soft-Start Function** – Limits inrush current during startup.  

The **MAX8620YETD+** is commonly used in **portable electronics, medical devices, and IoT applications** where efficiency and compact size are critical.  

(Note: Always refer to the official datasheet for detailed electrical characteristics and application guidelines.)
