Description and Introduction

1x/1.5x/2x White LED Charge Pump with Two LDOs in 4mm x 4mm Thin QFN The **MAX8631YETI+** 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)  
- **Package:** 16-TQFN (3x3mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (programmable)  
- **Number of Outputs:** 3 (two step-down DC-DC converters, one LDO)  
- **Switching Frequency:** Up to 2MHz  
- **Efficiency:** Up to 95% (for DC-DC converters)  

### **Descriptions:**  
The MAX8631YETI+ is a **high-efficiency, triple-output power supply IC** designed for portable applications. It integrates two **step-down (buck) DC-DC converters** and one **low-dropout (LDO) linear regulator**, providing a compact power solution for systems requiring multiple voltage rails.  

### **Features:**  
- **Dual Step-Down Converters:**  
  - High efficiency (up to 95%)  
  - Adjustable output voltages  
  - 600mA and 400mA output current capability  
- **Integrated LDO Regulator:**  
  - 150mA output current  
  - Low dropout voltage  
- **Power-Saving Modes:**  
  - Pulse-skipping mode for light-load efficiency  
  - Soft-start for controlled inrush current  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  
- **Small Footprint:**  
  - 16-pin TQFN (3mm x 3mm) package  

This IC is commonly used in **battery-powered devices, portable electronics, and embedded systems** requiring efficient power management.
