Description and Introduction

125mA 1x/1.5x Charge Pumps for 5 White LEDs in 3mm x 3mm TDFN The MAX8630WETD20+ 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 information:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8630WETD20+  
- **Package:** 20-TQFN (4x4)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (programmable)  
- **Number of Outputs:** 2 (Buck Regulators)  
- **Switching Frequency:** Up to 2MHz  
- **Current Output:** Up to 600mA per channel  
- **Efficiency:** Up to 95%  
- **Control Interface:** I²C (programmable output voltage and power sequencing)  

### **Descriptions:**  
The MAX8630WETD20+ is a dual-output, step-down (buck) DC-DC converter designed for portable applications. It integrates two high-efficiency PWM regulators with I²C-programmable output voltages, enabling dynamic power management. The device is optimized for battery-powered systems, offering low quiescent current and high efficiency across load conditions.  

### **Features:**  
- **Dual Synchronous Buck Regulators:** Two independent step-down converters with synchronous rectification.  
- **I²C Programmable Output Voltage:** Allows dynamic adjustment of output voltages via digital interface.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Power Sequencing Control:** Configurable soft-start and sequencing via I²C.  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Small Footprint:** 20-pin TQFN package (4mm x 4mm).  
- **Overcurrent and Thermal Protection:** Built-in safety features.
