Description and Introduction

18.5V, 2A, 650kHz / 1.2MHz Step-Up DC-DC Converter w/ Forced PWM Mode 8-VSSOP -40 to 85 The TPS61085DGKRG4 is a boost converter from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
TPS61085DGKRG4  

### **Description:**  
The TPS61085 is a high-efficiency, synchronous step-up DC-DC converter with an integrated 1.2-A switch. It is designed for applications requiring regulated output voltages from low input sources, such as single or dual-cell alkaline, NiMH, or lithium batteries.  

### **Key Features:**  
- **Input Voltage Range:** 0.9 V to 5.5 V  
- **Output Voltage Range:** Adjustable from 1.8 V to 5.5 V  
- **Integrated Synchronous Rectifier:** Improves efficiency by eliminating the need for an external Schottky diode  
- **High Switching Current Limit:** 1.2 A (typical)  
- **Fixed Switching Frequency:** 1.2 MHz (typical)  
- **Low Quiescent Current:** 28 µA (typical)  
- **Shutdown Current:** < 1 µA  
- **Thermal Shutdown Protection:** Yes  
- **Package:** 8-pin VSSOP (DGK)  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- Energy harvesting systems  
- Low-voltage power supplies  

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