High Power LED Driver
The ISL97801 is a high-power LED backlight driver with an
integrated 36V FET designed to drive up to 8 high-power
LEDs in series. The PWM converter runs from an internally
generated 1MHz clock. With efficiencies over 90% the
regulator provides tight control of LED current and may be
configured in either boost or buck topologies, allowing from 3
to 8 series diodes to be driven from wide input voltages.
LED light level may be controlled either by:
1. LED DC bias current set via the LEVEL pin, or
2. External low frequency PWM control via the
ENABLE/PWM pin.
In both control modes optional over temperature thermal
protection of the LED reduces the LED DC bias current
above an adjustable set temperature, protecting the LED
from thermal damage. An optional fault monitor drives an
external FET between the input supply and inductor,
providing short circuit current protection for the LED and
inductor as well as load dump protection for automotive
applications. For low cost applications the pass transistor
may be omitted and the fault pin bypassed.
The ISL97801 is packaged in a 20 Ld 4mm x 4mm QFN
package and is specified for operation over the -40°C to
+105°C temperature range.
