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