Description and Introduction

Step up DC-DC converter for LEDs The TB62731FU is a high-voltage, high-current Darlington transistor array manufactured by Toshiba. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Darlington Transistor Array  
- **Configuration:** 7-channel (7 Darlington pairs)  
- **Collector-Emitter Voltage (VCEO):** 50V (max)  
- **Collector Current (IC):** 500mA (max per channel)  
- **Input Voltage (VIH):** 5V (TTL/CMOS compatible)  
- **Output Type:** Open Collector  
- **Power Dissipation (PD):** 1.25W (per channel)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP20  

### **Descriptions:**  
The TB62731FU integrates seven Darlington transistor pairs with common emitters, designed for driving high-current loads such as relays, lamps, and LEDs. It includes built-in suppression diodes for inductive load protection and is compatible with TTL/CMOS logic levels.  

### **Features:**  
- **High-Voltage/High-Current Outputs** (50V, 500mA per channel)  
- **Integrated Clamp Diodes** for inductive load protection  
- **TTL/CMOS-Compatible Inputs** (simplifies interfacing with logic circuits)  
- **Low Input Current Requirement** (suitable for microcontroller applications)  
- **Compact SSOP20 Package** (space-saving design)  

This device is commonly used in industrial control systems, automotive applications, and display driving circuits.
