EUP2592 - 8-String White LED Driver

Description

The EUP2592 is an 8-channel WLED driver that controls WLED current for LCD backlight application.

The EUP2592 is capable of driving up to eight strings in parallel and 12 LEDs per string.

Features

  • an internal 150mΩ (typ. ), 48V (max. ) power MOSFET with local current-sense amplifier for accurate cycle-by-cycle current limit. This architecture greatly simplifies the external circuitry and saves PCB space. The EUP2592 minimizes the headroom voltage of output and power loss by detecting the highest LED forward voltage dynamically. Low-feedback voltage at each LED string 360mV (typ. ) at 20mA LED current helps reduce power loss and improve efficiency. The EUP2592 internally generates a PWM signa.

EUP2592 8-String White LED Driver for LCD Panel Application DESCRIPTION The EUP2592 is an 8-channel WLED driver that controls WLED current for LCD backlight application. The EUP2592 is capable of driving up to eight strings in parallel and 12 LEDs per string. Each string is terminated with ballast that achieves ±1.5% current regulation accuracy between strings, ensuring even LED brightness. The EUP2592 have wide input voltage range from 4.5V to 28V, and provide adjustable 5mA to 50mA LED current. EUP2592 uses an external PWM signal to control WLED dimming. EUP2592 has built in many fault protections. The EUP2592 step-up controller features an internal 150mΩ (typ.), 48V (max.) power MOSFET with local current-sense amplifier for accurate cycle-by-cycle current limit.
