Description and Introduction

Dual, Adjustable, 400mA and 600mA, 2.25MHz Step-Down Converter with 1-Wire Interface in QFN 10-VSON -40 to 85 The TPS62400DRCRG4 is a dual step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 400mA per channel  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSON-10 (3mm x 3mm)  
- **Control Method:** Fixed-frequency PWM with Power Save Mode  

### **Descriptions:**
- The TPS62400DRCRG4 is a dual synchronous step-down converter designed for low-power applications.  
- It integrates two independent DC-DC converters, each capable of delivering up to 400mA.  
- The device operates at a high switching frequency, allowing the use of small external components.  
- It supports Power Save Mode for improved efficiency at light loads.  

### **Features:**
- **Dual Outputs:** Two independent step-down converters in a single package.  
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectifiers.  
- **Low Quiescent Current:** 50µA (typical) per channel in Power Save Mode.  
- **100% Duty Cycle Operation:** Supports dropout operation for extended battery life.  
- **Soft Start:** Prevents inrush current during startup.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This device is commonly used in portable electronics, battery-powered applications, and space-constrained designs.
