RT8488
High Voltage 6-CH LED Driver Controller
General Description
The RT8488 is a 6-CH LED driver controller that delivers well matched LED current to each channel of LED string. With external current sources, the number of LEDs per string is only limited by the current source and the VIN/ VOUT conditions. The current mode PWM boost type controller operates at a programmable switching frequency of up to 1MHz, with a wide VIN range covering from 7V to 28V. The switch driver is designed to drive industrial grade high power MOSFETs.
The PWM loop selects and regulates the LED string with the highest voltage string to 0.7V, thus allowing voltage mismatches between the LED strings.
