Description and Introduction

SINGLE OR MULTI CELL LED DRIVER SOLUTION The ZXSC300E5TA is a high-efficiency step-up DC-DC converter manufactured by ZETEX (now part of Diodes Incorporated). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 0.8V to 5V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 500kHz  
- **Maximum Output Current:** 1A (dependent on external components)  
- **Quiescent Current:** Typically 40µA  
- **Efficiency:** Up to 90%  
- **Package:** SOT23-5  

### **Descriptions:**  
The ZXSC300E5TA is a low-voltage, high-efficiency DC-DC boost converter designed for battery-powered applications. It is optimized for driving white LEDs but can also be used for general step-up voltage conversion. The device includes a low-voltage comparator, a reference, and a high-current switch, requiring minimal external components.  

### **Features:**  
- **Low Start-Up Voltage:** Operates from inputs as low as 0.8V  
- **High Efficiency:** Optimized for battery-powered applications  
- **Adjustable Output:** Configurable for different output voltages  
- **Low Quiescent Current:** Extends battery life  
- **Compact Package:** SOT23-5 for space-constrained designs  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

SINGLE OR MULTI CELL LED DRIVER SOLUTION

Alternative Part Number

  • NCP1402SN33T1G --: Boost converter IC in SOT-23-5 with similar function and pinout, widely available and cost-effective replacement.
  • TPS61040DBVR --: Low-power boost converter in SOT-23-5 package with comparable input voltage range and switching behavior.
  • LT1932ES6#TRPBF --: Compact boost converter IC suitable for similar low-voltage step-up applications, though package is SOT-23-6.
  • AP3012KTR-G1 --: Boost converter in SOT-23-5 with similar operating voltage and output current, good alternative when ZXSC300 is unavailable.
