ISL97672AIRZ Produktdetails

The ISL97672A is an integrated 6-channel power LED driver for
LCD backlight applications. The ISL97672A is capable of
driving LEDs with input from 4.5V to 26.5V and maximum
output up to 45V.
The ISL97672A 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 ISL97672A 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 ISL97672A 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 ISL97672A is offered in a compact 20 Ld QFN 3x4 package
and can operate in ambient temperatures of -40°C to +85°C.
