Littelfuse, Inc., a global leader in circuit protection, today announced the PLEDxN family of LED open circuit protectors. These surface mount devices are designed to work with high-brightness 1 watt LEDs with a nominal current of 350 mA at 3 V, which provides a switched electronic shunt when an LED string or an LED in the array has an open circuit fault. It can be automatically reset after the LED self-recovery or power cycle.

Linear Technology Corporation, a subsidiary of Analog Devices, Inc. (ADI), introduced the LT8645S, an 8A, 65V input synchronous step-down switching regulator. Its unique Silent Switcher® 2 architecture uses two internal input capacitors and internal BST and INTVCC capacitors to minimize thermal loop area. Combining a very well-controlled switch edge with an internal construction with an integral ground plane and a copper post instead of a bond wire, the LT8645S is designed to significantly reduce EMI / EMC emissions.
