Description and Introduction

125mA 1x/1.5x Charge Pumps for 5 White LEDs in 3mm x 3mm TDFN The MAX8630XETD20+ 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  
- **Part Number:** MAX8630XETD20+  
- **Package:** 20-Pin TQFN-EP (5x5mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Number of Outputs:** 2 (Buck Regulators)  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Load Current:** Up to 600mA per channel  

### **Descriptions:**  
The MAX8630XETD20+ is a **dual-output, step-down (buck) DC-DC converter** designed for portable and battery-powered applications. It integrates two high-efficiency PWM regulators with synchronous rectification, minimizing external components.  

### **Features:**  
- **Dual Synchronous Buck Regulators** (600mA each)  
- **1MHz Fixed Switching Frequency** (reduces inductor size)  
- **Low Dropout Operation** (100% duty cycle)  
- **Internal Soft-Start** (reduces inrush current)  
- **Power-Good Output** (monitors regulator status)  
- **Low Quiescent Current** (improves battery life)  
- **Thermal Overload Protection**  
- **Undervoltage Lockout (UVLO)**  

This IC is commonly used in **smartphones, tablets, portable media players, and other handheld devices** requiring efficient power management.  

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