Maxim Integrated
General Description
The MAX16801A/B/MAX16802A/B high-brightness (HB) LED driver-control ICs contain all the circuitry required
for the design of wide-input-voltage-range LED drivers for general lighting and display applications. The
MAX16801 is well suited for universal input (rectified 85VAC to 265VAC) LED drivers, while the MAX16802 is
intended for low-input-voltage (10.8VDC to 24VDC) LED drivers.
