Description and Introduction

18.5V, 2A, 650kHz, 1.2MHz Step-Up DC-DC Converter with Forced PWM Mode (extended temp range) 8-TSSOP -40 to 105 The TPS61085T is a boost converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.9V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Maximum Output Current:** 1.2A (at 3.3V output from a 1.8V input)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin WSON (3mm × 3mm)  

### **Descriptions:**  
- The TPS61085T is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications.  
- It integrates a synchronous rectifier to improve efficiency and reduce external component count.  
- The device supports automatic power-save mode for light-load efficiency.  

### **Features:**  
- **Wide Input Voltage Range:** Suitable for single-cell or multi-cell battery applications.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** 15µA (typical) to extend battery life.  
- **Integrated Power Switch:** Simplifies design and reduces BOM.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent and Thermal Protection:** Ensures safe operation.  
- **Synchronous Rectification:** Improves efficiency compared to diode-based solutions.
