Description and Introduction

Adjustable, 800-mA, 10V Vin, Enhanced LBI, Step-Down Converter in MSOP-10 The TPS62051DGS is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS62051DGS  

### **Specifications:**  
- **Input Voltage Range:** 2.9V to 6V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Pin VSSOP (DGS)  

### **Descriptions:**  
The TPS62051DGS is a high-efficiency, synchronous step-down DC-DC converter designed for low-power applications. It operates at a fixed frequency of 1.5MHz, allowing the use of small external components. The device features a power-save mode for improved efficiency at light loads, making it suitable for battery-powered applications.  

### **Features:**  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **100% Duty Cycle Operation:** Supports low dropout conditions.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** 10-pin VSSOP package (3mm x 3mm).  

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

Application Scenarios & Design Considerations

Adjustable, 800-mA, 10V Vin, Enhanced LBI, Step-Down Converter in MSOP-10

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 in SOT-23-5 with wide input range and adjustable output, offering similar efficiency and a different naming series for easy distinction.
  • MP1584EN-LF-Z --: Widely available step-down converter with higher current capability and adjustable output; requires minor layout adjustment but is a cost-effective alternative from a different vendor series.
  • TPS62050DGS --: Same TPS6205x family buck converter in the same DGS package with nearly identical specifications; the main difference is the output voltage setting, so it is a close drop-in substitute.
  • TPS62203DBV --: Similar step-down converter from a different TI series, offering comparable input range and load capability in a small SOT-23 package; verify pinout and output voltage before use.
  • LTC3406ES5 --: Alternative high-efficiency synchronous buck converter from another vendor with similar current rating and compact package; requires layout and pinout review.
