Description and Introduction

Adjustable, 500-mA, 3-MHz Step-Down Converter in QFN or Chip-Scale The TPS62300YZDT is a high-efficiency, synchronous step-down DC-DC converter manufactured by Texas Instruments (TEXAS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.77V to 5.5V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin DSBGA (YZD)  

### **Descriptions:**
- The TPS62300 is a high-frequency, synchronous step-down converter optimized for battery-powered portable applications.  
- It provides high efficiency across a wide load current range, making it suitable for power-sensitive devices.  
- The device integrates low RDS(on) MOSFETs to minimize power loss.  
- It supports a forced PWM mode for low output voltage ripple and a Power Save mode for improved efficiency at light loads.  

### **Features:**
- **High Efficiency:** Up to 95% efficiency due to synchronous rectification.  
- **Low Quiescent Current:** 15µA in Power Save mode for extended battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **100% Duty Cycle Mode:** Allows operation at very low input voltages.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation under fault conditions.  
- **Small Footprint:** Compact 8-pin DSBGA package for space-constrained applications.  

This information is based solely on the manufacturer's datasheet for the TPS62300YZDT.

Application Scenarios & Design Considerations

Adjustable, 500-mA, 3-MHz Step-Down Converter in QFN or Chip-Scale

Alternative Part Number

  • LM3671MF-1.2 --: Pin-compatible step-down DC-DC converter in SOT-23 with similar 1.2V fixed output and comparable current rating, widely available and easy drop-in for many TPS62300 designs.
  • AP3418KTR-G1 --: 1.2V fixed-output synchronous buck converter in small package with similar input range and load capability, offering a lower-cost alternative from a different series.
  • RT8059GJ5 --: Compact 1.2V step-down converter with comparable switching frequency and current handling, suitable as a functional replacement when layout adjustments are acceptable.
  • TPS62200DDCR --: Same family of step-down converters with similar input voltage range and output current, available in SOT-23 package; a common drop-in choice when the YZD package is unavailable.
  • LTC3406ES5#TRPBF --: Pin-compatible-class 600mA synchronous buck converter with comparable switching frequency and efficiency, suitable as a cross-vendor replacement for low-power portable designs.
  • AP3402KTR-G1 --: Low-cost 2A synchronous step-down converter with similar input range and small package, offering a cost-effective alternative for space-constrained applications.
