ISL78100ARZ-T7A - Renesas Electronics

Description: 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: LED DC bias current set via the LEVEL pin, or External low f
