Description and Introduction

ADJUSTABLE LED DRIVER WITH INTERNAL SWITCH IN TSOT23-5 The ZXLD1101ET5TA is a step-up DC-DC converter manufactured by ZETEX (now part of Diodes Incorporated).  

### **Specifications:**  
- **Input Voltage Range:** 0.8V to 5.5V  
- **Output Voltage:** Adjustable via external resistors  
- **Switching Frequency:** 1MHz (typical)  
- **Maximum Output Current:** Up to 100mA (depending on input/output conditions)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions and Features:**  
- Designed for low-voltage applications, including single-cell battery-powered devices.  
- Integrated power switch for compact designs.  
- Low start-up voltage (as low as 0.8V).  
- Adjustable output voltage using external resistors.  
- High efficiency for extended battery life.  
- Over-temperature protection.  
- Small footprint, suitable for space-constrained applications.  

This device is commonly used in portable electronics, energy harvesting, and low-power sensor applications.

Application Scenarios & Design Considerations

ADJUSTABLE LED DRIVER WITH INTERNAL SWITCH IN TSOT23-5

Alternative Part Number

  • LT1932ES6#TRMPBF --: Constant-current LED driver in a small SOT-23 package with comparable boost topology and current regulation, widely used as a direct functional substitute for the ZXLD1101.
  • AP3019AKTR-G1 --: Boost-type white LED driver with internal switch and similar input voltage range, offering a cost-effective drop-in alternative for backlight applications.
  • TPS61165DRVR --: High-efficiency boost LED driver with PWM dimming and integrated switch, suitable replacement when higher current capability and flexible dimming are needed.
