Switching at 2 MHz — inductor size and EMI
The MAX16822BASA+T: The 2 MHz fixed switching frequency keeps the inductor physically small — typically a 10 µH to 22 µH shielded ferrite — and pushes the fundamental switching noise above the AM radio band, easing input filter design for automotive EMC compliance.
350 mA per channel with PWM dimming: driving the LED current
Rated 350 mA per channel with an internal switch, the part delivers constant-current regulation to a single LED string; PWM dimming on the DIM pin allows wide-range brightness control without colour shift — the dimming ratio depends on the PWM source frequency and the output capacitor hold-up time.
Package and temperature grade for the board stack
Housed in an 8-SOIC with 0.154-inch body width, the part fits a standard SOIC footprint with 1.27 mm pin pitch.
