Allegro announces LC5220D/S LED drivers

Allegro MicroSystems, Inc. has released a new simple and efficient family of LED driver ICs that can be configured as buck or buck-boost voltage converters. The LC5220D/S LED series is offered by Allegro and manufactured and developed by Sanken Electric Co., Ltd. in Japan. This family is targeted at the consumer market with end applications such as LED lighting fixtures and LED light bulbs.

These non-isolating devices operate off-line, having a high voltage capacity that permits direct connection to a wide range of supply voltages (from 25 to 400 V recommended). The LC5220 series uses PWM and constant current mode to drive LEDs with adjustable dimming. Each device includes a power MOSFET and controller IC as well as built-in protection and energy-saving functions.

These devices are available in standard through hole or surface mount packages. The LC5220 series is an updated version of the LC5200 series, and integrates most of those functions, while increasing the selection of AC input voltages and providing better protection features, for fewer peripheral components.
