It integrates the switching FET internally and provides two output channels with PWM dimming control, switching at 1 MHz to keep external inductor and capacitor values small.
Housed in a 10-bump TµSMD package (1.9 x 2.07 mm), this is a wafer-level chip-scale package requiring a fine-pitch PCB footprint and careful solder-paste stencil design for reliable assembly.
Available inventory is limited to surplus and broker stock.
