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 35mA 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
150m
(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 signal for
accurate
WLED
dimming
control.
The
PWM
frequency is resistor programmable, while PWM duty
cycle is controlled directly from an external PWM
signal or through an adjustable resistor at PWMO pin.
This internal PWM dimming control provides a
dimming range with 8-bit resolution to maximize
battery life. The EUP2592 WLED brightness can also
be directly modulated with an external PWM signal
from 100Hz to 10kHz.
The EUP2592 have extensive protection that include
string open and short detection, over voltage protection,
over-temperature protection and an optional input
over-current
protection
with
an
external
fault
disconnect switch.
