Description and Introduction

Dual, Adjustable, 600mA and 1000mA, 2.25MHz Step-Down Converter with 1-Wire Interface in QFN 10-VSON -40 to 85 The TPS62420DRCR is a dual-channel, step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.3 V to 5.5 V  
- **Output Voltage Range:** Adjustable from 0.6 V to VIN  
- **Output Current:** Up to 600 mA per channel (1.2 A total)  
- **Switching Frequency:** 2.25 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin VSON (DRC)  

### **Descriptions:**  
- The TPS62420DRCR is a synchronous, step-down (buck) converter optimized for portable battery-powered applications.  
- It integrates two independent converters in a single package, reducing board space.  
- Features a fixed-frequency PWM mode for low-noise operation and automatic PFM/PWM mode switching for improved efficiency at light loads.  

### **Features:**  
- **Dual Outputs:** Two independent 600 mA converters.  
- **High Efficiency:** Up to 95% with Power Save Mode (PFM).  
- **Low Quiescent Current:** 28 µA (typical) per channel in PFM mode.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Soft Start & Short-Circuit Protection:** Prevents inrush current and output faults.  
- **Synchronizable:** Allows synchronization to an external clock.  
- **Small Footprint:** 10-pin VSON package (3 mm × 3 mm).  

This device is commonly used in smartphones, portable medical devices, and other battery-powered systems requiring efficient power management.
