The A8513KLYTR-T from Allegro Microsystems is a fault-tolerant, high-efficiency LED driver IC designed for LCD backlighting applications. It integrates a current-mode boost converter with an internal power switch and a single current sink.
This device features a wide input voltage range from 4.5V to 40V, making it suitable for applications with varying power supply conditions such as automotive start/stop, cold crank, and load dump scenarios. The boost converter operates at a switching frequency of up to 2 MHz, allowing it to function above the AM radio band. It can drive up to 14 series LEDs with a maximum LED current of 150 mA.
The A8513KLYTR-T offers a single EN/PWM pin for both PWM dimming and enable functions, providing a 5000:1 dimming ratio at 200 Hz. It includes comprehensive protection features such as output short and overvoltage protection, open or shorted LED pin protection, and IC overtemperature protection. The device is available in a 10-pin MSOP package with an exposed thermal pad for enhanced thermal dissipation.
Key applications include automotive infotainment systems, automotive clusters, automotive center stacks, industrial LCD displays, and LED lighting. Its robust design and integrated features make it a versatile solution for demanding backlighting requirements.
