Maxim MAX16801A/B and MAX16802A/B LED Driver Datasheet
The MAX16801A/B and MAX16802A/B are high‑brightness LED driver‑control ICs designed for universal‑input (85 VAC‑265 VAC) and low‑input (10.8 VDC‑24 VDC) applications. They support buck, boost, flyback, SEPIC and other topologies, offering a fixed 262 kHz switching frequency and programmable duty cycles of 50 % or 75 %.
Key features include an internal error amplifier with 1 % accurate reference, UVLO/EN programmable input startup voltage, internal bootstrap UVLO (MAX16801 only), thermal shutdown at 130 °C, and a tiny 8‑pin UMAX package operating from –40 °C to +85 °C.
