ISL97672BIRZ規(guī)格書(shū)詳情

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.
