Worcester, MA – September 2012 – Allegro MicroSystems, Inc. announces the release of 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 new series is targeted at the consumer market with end applications to include LED lighting fixtures and LED light bulbs. 

These non-isolating devices operate off-line, having a high voltage capacity that allows 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 incor­porates a power MOSFET and controller IC as well as built-in protection and energy-saving functions, reducing external parts required, and making the LC5220 ideal for use in small-size LED light bulbs.

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