Description and Introduction

Thin SOT23 750mA Load Step-Down DC-DC Regulator The LM2736XMKX is a switching regulator IC manufactured by Texas Instruments (NS). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:** Adjustable from 1.258V to 16V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 550 kHz or 1.6 MHz (selectable)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-6 (XMK)  

### **Descriptions:**  
The LM2736XMKX is a step-down (buck) DC-DC converter designed for high-efficiency power conversion. It integrates a high-side N-channel MOSFET and is optimized for low-voltage, high-current applications.  

### **Features:**  
- **Wide Input Voltage Range** (3V to 20V)  
- **Adjustable Output Voltage** (1.258V to 16V)  
- **High Switching Frequency** (550 kHz or 1.6 MHz)  
- **Integrated N-Channel MOSFET**  
- **Thermal Shutdown Protection**  
- **Cycle-by-Cycle Current Limiting**  
- **Low Shutdown Current (<1μA)**  
- **Small SOT-23 Package**  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Thin SOT23 750mA Load Step-Down DC-DC Regulator

Alternative Part Number

  • TPS54231DR --: Pin-compatible step-down converter with similar input voltage range and current rating; TI is the successor to National Semiconductor, so it is a direct functional replacement.
  • MP1584EN --: Wide-input buck converter with comparable switching frequency and output current, commonly used as a drop-in alternative for LM2736 designs.
  • AP3211KTR-G1 --: 1.5A step-down converter with similar voltage range and SOT-23 package, suitable as a lower-cost alternative with equivalent function.
