Description and Introduction

Low VBATT, 20µA IQ, 1MHz Synchronous Boost Converter with True Shutdown The MAX8627ETD+ 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:  

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

### **Specifications:**  
- **Package:** **TDFN-EP (14-Pin, 3x3mm, Exposed Pad)**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Input Voltage Range:** **2.7V to 5.5V**  
- **Output Voltage:** **Adjustable (via external resistors)**  
- **Output Current:** **Up to 1.5A (per channel, depending on configuration)**  
- **Switching Frequency:** **Up to 2MHz (adjustable)**  
- **Efficiency:** **Up to 95% (depending on load and conditions)**  
- **Number of Outputs:** **Dual (two independent step-down regulators)**  

### **Descriptions:**  
- The **MAX8627ETD+** is a **dual, high-efficiency, step-down DC-DC converter** designed for portable and battery-powered applications.  
- It integrates **two synchronous buck regulators** with low RDS(ON) MOSFETs for high efficiency.  
- Features **PWM (Pulse-Width Modulation) and PFM (Pulse-Frequency Modulation) modes** for optimized efficiency across load ranges.  
- Includes **soft-start, overcurrent, and thermal shutdown protection** for robust operation.  

### **Features:**  
- **Dual Independent Step-Down Regulators** (1.5A each)  
- **Adjustable Output Voltages** (via external resistors)  
- **High Efficiency (up to 95%)**  
- **2MHz Switching Frequency** (reduces external component size)  
- **Low Quiescent Current (30µA per channel in PFM mode)**  
- **Synchronous Rectification** (improves efficiency)  
- **Soft-Start & Protection Circuits** (overcurrent, thermal shutdown)  
- **Tiny 14-Pin TDFN-EP Package** (suitable for space-constrained designs)
