Boost LED driver for backlight strings
It integrates the switching FET and delivers up to 26 V output to drive a series LED string, with PWM dimming for brightness control.
Switch current and output voltage ceiling
For a typical backlight string of six to eight white LEDs in series, the 26 V headroom accommodates the forward voltage stack plus the sense resistor drop. Operating from a supply range of 2.7 V to 18 V, it can run off a single lithium-ion cell or a 12 V rail. The 600 kHz switching frequency keeps the inductor small, which helps the 6-WSON (2x2 mm) package fit tight handheld or panel-edge layouts.
Temperature grade and deployment fit
It does not carry an automotive-grade qualification, so it is not specified for under-hood or cabin-temperature excursions above 85°C.
