Description and Introduction

18.5V, 3.2A, 650kHz / 1.2MHz Step-Up DC-DC Converter with Forced PWM Mode 10-VSON -40 to 85 The TPS61087DRCT is a boost converter manufactured by Texas Instruments (TI). Below 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 2A  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Package:** 10-pin VSON (DRC)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:**  
  - Integrated 2A, 30mΩ power switch  
  - Adjustable output voltage  
  - Power-saving mode for light-load efficiency  
  - Overcurrent and thermal protection  
  - Soft-start function  

### **Description:**  
The TPS61087DRCT is a high-efficiency, synchronous step-up DC-DC converter designed for battery-powered applications. It integrates a low-resistance power switch to minimize power loss and supports a wide input voltage range, making it suitable for single-cell Li-ion or multi-cell alkaline/NiMH applications.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Adjustable Output:** External resistor divider allows flexible output voltage setting.  
- **Low Quiescent Current:** 17µA (typical) in power-saving mode.  
- **Protection Features:** Overcurrent, thermal shutdown, and undervoltage lockout (UVLO).  
- **Small Footprint:** 10-pin VSON package (3mm × 3mm) for space-constrained designs.  

This information is sourced from the TI datasheet for the TPS61087DRCT.
