产品概述 返回TOPLGt嘉泰姆
CXLE8115 is a highly integrated and cost effective Light
Emitting Diode (LED) driver optimized for LCD monitor
and LCD TV backlighting application. It provides a high
performance LED backlight solution with minimized
BOM count. LGt嘉泰姆
The CXLE8115 contains a PWM boost driver which uses
current mode control and fixed frequency operation to
regulate the LED current. The LED current is sensed
through an external current sense resistor. The
voltage across the sensing resistor is compared with
reference level of 200mV, the error is amplified to
control the pulse width of the power switch thus to
regulate the current flowing the LED.
The CXLE8115 offers external low frequency PWM
(LPWM) dimming method for a wide range of dimming
control.
The CXLE8115 offers comprehensive protection such as
power MOSFET over current protection (OCP), output
over voltage protection (OVP), IC power supply under
voltage lockout (UVLO), and LED open protection
