Introduction

AI Translation

DIO5661 is a serial white LED driver, featuring an architecture of 86% high-efficiency current mode boost converter, driving up to 10 serial LEDs or a 3x13(3LEDs in rows) LED matrix. And it adopts PWM to Constant Current dimming control mode, with wide frequency range from 200Hz to 200kHz (The dimming frequency above 10kHz is recommended). The serial configuration assures the very most brightness consistency of the whole LED array. DIO5661 works on 1.1MHz switching frequency, which can maximize current output of 1.3A limit and achieve high current conversion efficiency and result in external compact component size. Additionally, the total external component number is minimized due to the integrated low-side power MOSFET. DIO5661 integrates multiple protection features, such as LED open-circuit protection, thermal shutdown protection and cycle-by-cycle input current limit protection. And the built-in soft start circuit limits inrush current when the circuit starts.
