Introduction

AI Translation

TP8018 is a buck LED constant-current driver operating in fixed off-time control mode, designed for efficient driving of multiple LEDs. It employs a closed-loop average current control scheme, making the output current insensitive to inductance variations in system applications, thereby improving constant-current accuracy. It is suitable for non-isolated buck LED constant-current driver circuits with an input voltage range of 5~100V. An integrated power transistor allows the average LED output current to be set via an external resistor. The application circuit is streamlined, requiring minimal external components to achieve high-accuracy LED output, reducing system cost and board space. Multiple protection features are integrated to ensure system stability and reliability, including LED output short-circuit protection, LED output overcurrent protection, intelligent chip temperature control, and VDD undervoltage lockout protection.
