Description and Introduction

3.3-V Output, 800-mA, 10V Vin, 95% Efficient Step-Down Converter in MSOP-10 The TPS62056DGSR is a step-down converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin VSSOP (DGS)  

### **Descriptions:**  
The TPS62056DGSR is a high-efficiency, synchronous step-down DC-DC converter designed for low-power applications. It operates with a fixed-frequency PWM mode and automatically switches to Power Save Mode (PSM) at light loads to improve efficiency.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectification.  
- **Low Quiescent Current:** 17µA typical for improved battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power Save Mode (PSM):** Enhances light-load efficiency.  
- **100% Duty Cycle Operation:** Supports low dropout conditions.  
- **Soft Start:** Reduces inrush current.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** 10-pin VSSOP package for space-constrained designs.  

This information is sourced from TI's official datasheet for the TPS62056DGSR.

Alternative Part Number

  • LTC3406ES5#TRPBF --: Pin-compatible step-down converter in a similar SOT-23-5 package with comparable input voltage range and output current, suitable as a direct functional replacement.
  • AP3211KTR-G1 --: 1A synchronous buck converter with similar input voltage range and adjustable output, available in a small SOT-23-5 package for drop-in style substitution.
  • MP2145GD-Z --: High-efficiency synchronous step-down converter with comparable current rating and input voltage range, offering a viable alternative when layout adjustments are acceptable.
  • TPS62133RGTR --: Same vendor buck converter family with similar 3A output and adjustable output voltage, different package and series prefix, good drop-in for many TPS62056 designs.
  • LTC3605EUF#PBF --: High-efficiency 3A synchronous buck converter with comparable input range and adjustable output, from a different manufacturer and naming series.
