Description and Introduction

250-mA, 1.5-V High-Efficiency Step-Down Charge Pump The TPS60503DGS is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Output Voltage:** Fixed 3.3V or adjustable (1.2V to 5.5V)  
- **Output Current:** Up to 500mA  
- **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 TPS60503DGS is a high-efficiency, low-power step-down DC-DC converter designed for battery-powered applications. It integrates a synchronous rectifier to minimize external components and improve efficiency. The device operates in pulse-frequency modulation (PFM) mode at light loads to maximize efficiency and transitions to pulse-width modulation (PWM) mode under higher loads.  

### **Features:**  
- **Low Quiescent Current:** 17µA (typical) extends battery life.  
- **High Efficiency:** Up to 95% conversion efficiency.  
- **Synchronous Rectification:** Reduces power loss and improves efficiency.  
- **Fixed and Adjustable Output Options:** Supports 3.3V fixed or adjustable output (1.2V to 5.5V).  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  
- **Thermal Shutdown and Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** 10-pin VSSOP package (3mm x 3mm).  

This information is based on TI's official datasheet and product documentation.
