Boost regulator with PWM dimming for LCD backlight
It delivers a regulated 44V output across two independent channels, each capable of driving LED strings with an internal switch rated at 750mA. PWM dimming input on the control pin lets the host processor or a dedicated backlight controller adjust LED brightness without audible noise — a common requirement in automotive infotainment screens and handheld instruments where the display must dim cleanly across the full range.
Supply rails and temperature envelope
Input supply range runs from 2.5V up to 5.5V, so it works off a single lithium-ion cell, a 3.3V rail, or a 5V USB bus.
