概要
説明
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 frequency PWM control via the ENABLE/PWM pin.

Processing table
Tips for Using This Parametric Table:
- Hide Filters button in header: Collapse or expands filters
- Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
- Reset button in header: Reset all filters to the page default
- Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
- Export button in header: Export the filtered results of the table to an Excel document
- Filter parts search bar in header: Type to filter table results by part number
- Hide column button in column headers: Select to hide columns in table
- AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
- Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
