Description and Introduction

250-mA, 1.5-V High-Efficiency Step-Down Charge Pump 10-VSSOP -40 to 85 The TPS60503DGSG4 is a charge pump DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 1.8 V to 6.5 V  
- **Output Voltage:** 3.3 V (fixed)  
- **Output Current:** Up to 250 mA  
- **Efficiency:** Up to 95%  
- **Switching Frequency:** 1.2 MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** MSOP-10 (DGS)  

### **Description:**  
The TPS60503DGSG4 is a low-noise, regulated charge pump DC-DC converter that provides a fixed 3.3 V output from an input voltage range of 1.8 V to 6.5 V. It is designed for applications requiring low noise and high efficiency in a compact form factor.  

### **Features:**  
- **Low Noise:** Uses a regulated charge pump architecture to minimize output ripple.  
- **High Efficiency:** Up to 95% efficiency with no inductors required.  
- **Low Quiescent Current:** 65 µA (typical) in operation, 1 µA (typical) in shutdown mode.  
- **Automatic Power-Save Mode:** Enhances efficiency at light loads.  
- **Short-Circuit Protection:** Includes thermal shutdown and current limiting.  
- **Small Footprint:** 10-pin MSOP package for space-constrained applications.

Application Scenarios & Design Considerations

250-mA, 1.5-V High-Efficiency Step-Down Charge Pump 10-VSSOP -40 to 85

Alternative Part Number

  • LM3671MF-3.3 --: Pin-compatible step-down converter in the same TI family with similar 3.3V fixed output and small package, suitable as a drop-in replacement for many TPS60503 applications.
  • TPS62203DBVR --: TI buck converter with comparable input range and 3.3V output, offering similar efficiency and a different series naming for easy distinction.
  • AP3211KTR-G1 --: Alternative 3.3V step-down regulator from a different manufacturer with comparable current capability and SOT-23 package, useful as a second-source option.
