Description and Introduction

White LED Charge Pump with Mono Class D Audio Amp and Dual LDO The MAX8821ETI+ is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (N/A indicates no specific brand alternative)  
- **Package:** 28-TQFN (5x5mm)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Number of Outputs:** 2 (Buck and LDO)  
- **Buck Converter Efficiency:** Up to 95%  
- **LDO Output Current:** Up to 300mA  
- **Switching Frequency:** 1MHz (fixed)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX8821ETI+ is a highly integrated power management IC designed for portable and battery-powered applications. It combines a high-efficiency step-down (buck) DC-DC converter and a low-dropout (LDO) linear regulator in a single package. The device is optimized for space-constrained designs requiring multiple regulated voltages.  

### **Features:**  
- **Dual Outputs:**  
  - **Buck Converter:** Delivers up to 600mA with high efficiency.  
  - **LDO Regulator:** Provides 300mA with low dropout voltage.  
- **Low Quiescent Current:** 30µA (typical) in standby mode.  
- **Power-Good (PG) Output:** Monitors buck converter output.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Compact Footprint:** 28-pin TQFN package (5mm x 5mm).  

This information is strictly factual and based on the manufacturer's datasheet. No additional guidance or suggestions are included.
