ISL97672B规格书详情
The ISL97672B is an integrated 6-channel power LED driver for
LCD backlight applications. ISL97672B is capable of driving
LEDs with input from 4.5V to 26.5V and maximum output up to
45V.
The ISL97672B employs an adaptive boost switching
architecture that allows Direct PWM dimming with dimming
duty cycle as low as 0.007 at 200Hz or 0.8 at 20kHz. PWM
Dimming frequency can be as high as 30kHz.
The ISL97672B employs the dynamic headroom control that
monitors the highest LED forward voltage string for output
regulation to minimize headroom voltage and power loss in a
typical multi-string operation. Typical current matching between
channels is ±0.7.
The ISL97672B incorporates extensive protection functions
that flag whenever a fault occurs. The protections include
string-open and short-circuit detections, OVP, OTP, and an
optional output short-circuit protection with external fault
disconnect switch
The ISL97672B is offered in a compact 20 Ld QFN 3x4
package and can operate in ambient temperatures of -40°C to
+85°C.
