MP3022

The MP3022 is a WLED driver that can drive up to 4 backlight WLEDs at up to 30mA each. Backlight brightness is adjusted using a 5 bit register plus one bit for precise low brightness control.
The MP3022 employs a super efficient inductorless charge pump with 1x, 1.5x, and 2x automatic mode control to achieve high efficiency power conversions.
Monolithic Power System’s single wire MPCTM serial data link provides a simple and fast interface used to enable, disable, and set current levels for each LED. In addition, soft start limits the inrush current during startup and mode switching.
Each output is current limited, providing controlled brightness and short circuit protection. Thermal shutdown protection guards against excessive temperatures due to circuit loads and shorts.
The tiny 3mm x 3mm QFN 16-pin package and small external capacitors deliver the most compact white LED solution available.
