Description and Introduction

18.5V, 2A, 650kHz / 1.2MHz Step-Up DC-DC Converter w/ Forced PWM Mode 8-TSSOP -40 to 85 The TPS61085PWR is a boost converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 28µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin HTSSOP (PWR)  

### **Descriptions:**  
The TPS61085PWR is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It integrates a 1.2A switch and supports low input voltage operation, making it suitable for single-cell Li-ion or dual/three-cell alkaline/NiMH battery systems.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 1.8V to 5.5V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Up to 95% with Power Save Mode for light loads.  
- **Low Quiescent Current:** 28µA (typical) for extended battery life.  
- **Integrated Power Switch:** 1.2A current limit.  
- **Fixed Switching Frequency:** 1.2MHz for reduced external component size.  
- **Thermal Shutdown & Overcurrent Protection:** Built-in safety features.  
- **Small Footprint:** 10-pin HTSSOP package for space-constrained designs.
