ISL78100
High Power LED Driver
The ISL78100 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.
