Description and Introduction

3.6-V 95% Efficient Boost Converter with 3.3-V 200-mA LDO for 1-Cell LiIon or Dual-Cell Applications The TPS61122PW is a DC-DC boost converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 1.8V to 6V  
- **Output Voltage Range:** Adjustable up to 28V  
- **Output Current:** Up to 30mA (depending on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-pin TSSOP (PW)  

### **Descriptions:**
The TPS61122PW is a high-efficiency, low-quiescent-current boost converter designed for applications requiring a regulated high-voltage output from a low-voltage input. It integrates a power switch and supports adjustable output voltage through an external resistor divider. The device is optimized for battery-powered systems, such as OLED displays and other portable electronics.

### **Features:**
- **Wide Input Voltage Range:** Supports operation from 1.8V to 6V.  
- **High Output Voltage:** Adjustable up to 28V.  
- **Integrated Power Switch:** Simplifies design and reduces external components.  
- **Low Quiescent Current:** Typically 30µA (improves battery life).  
- **Fixed Switching Frequency:** 1.2MHz minimizes external component size.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Package:** 14-pin TSSOP (PW) for space-constrained applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
