MAX16841
Controller IC for Dimmable Offline LED Lamps
General Description
The MAX16841 is an LED driver for AC line (100V, 120V,
220V, and 230V AC) input lamps. It features proprietary
control of the input current that allows lamps to dim
smoothly from full to zero light intensity, while providing
active power factor correction (PFC). It is a very flexible
product that can be used in isolated (e.g., flyback) and
nonisolated (e.g., buck) configurations. The conventional
use of an optocoupler in isolated configurations can be
avoided in MAX16841-based designs.
The constant frequency-control technique of the
device allows maximization of the conversion efficien-
cy at both low and high AC line by operating at the
conduction mode that minimizes total conduction and
switching losses.
The device can be configured for universal input (90V to
264V AC) dimmable applications, allowing the design of an
LED lamp that can be operated and dimmed worldwide.
This device can be used without electrolytic capacitors,
thus maximizing the lamp lifetime. In this case, the LED
current is a rectified sinusoid with a frequency that is
twice the AC line frequency.
The device also features thermal shutdown, current limit,
open LED protection, and V CC undervoltage lockout.
The MAX16841 is available in an 8-pin SO package and
