[原创] Infineon ILD6150 60V 1.5A高效降压LED驱动方案

Infineon公司的ILD6150是60V/1.5A高效降压LED驱动器,电源电压从4.5V到60V,开关频率高达1MHz,软起动功能,模拟和PWM调光,输出电流精度3%,LED电流温度漂移很低,效率高达98%,主要用在通用照明的LED驱动器,街道和隧道照明以及办公室和住宅区照明.本文介绍了ILD6150主要特性,框图,应用电路,以及ILD6150 60V/1A演示板电路,电路图,材料清单和PCB布局图.

The ILD6150 is a hysteretic buck LED driver IC for driving high power LEDs in general lighting applications with average currents up to 1.5 A.

The ILD6150 is suitable for LED applications with a wide range of supply voltages from 4.5 V to 60 V. A multifunctional PWM input signal allows dimming of the LEDs with an analog DC voltage or an external PWM signal. To minimize colorshifts of the LEDs an analog PWM voltage is converted to an internal 1.6 kHz PWM signal modulating the LED current.
