Op amp for LED driving compatible with analog or PWM dimming signals

The onsemi NCL38046 amplifier gives precise regulation of the constant current/constant voltage outputs on the secondary side of an ac-dc LED driver. The amplifier enables deep dimming and a low-power standby mode.

Extension of SiC power device portfolio brings robust 1,700 V capability to MOSFETs and diodes

The EliteSiC family from onsemi incorporates a broad set of silicon carbide (SiC) MOSFETs, diodes, SiC modules, and hybrid SiC/silicon modules, and a new 1,700 V rating for higher-voltage applications.
