The Maxim MAX16801A/B and MAX16802A/B are high-brightness LED driver control ICs that contain all circuits needed for boost, buck, flyback, SEPIC and other topologies. The MAX16801 supports universal offline input from rectified 85V AC to 265V AC, while the MAX16802 supports low-voltage input from 10.8V DC to 24V DC.
Both devices provide precision LED current control using an internal error amplifier and 1% reference, with PWM or analog dimming. They operate at a fixed 262kHz frequency, offer maximum duty cycles of 50% (A versions) or 75% (B versions), and come in an 8-pin package rated for -40°C to +85°C. This manual is written in Chinese.
