Power Integrations Released Seven New LED Diver Ics

Power Integrations has added seven new members (LNK413-LNK419) to its popular LinkSwitch-PH family of LED driver ICs.

The new devices can achieve up to 88% efficiency, feature a PWM-dimmable single-stage controller with both power factor correction and accurate constant current power conversion functionality.

In addition, LinkSwitch-PH devices incorporate the PFC/CC controller, a 725 V MOSFET and MOSFET driver into a single package. The new ICs enable the ultimate in high reliability at low cost by eliminating up to 25 additional components used in traditional isolated flyback designs, including the high-voltage electrolytic bulk capacitor and the optocoupler.

They are suitable for lighting applications ranging from 3 W bulbs to 55 W replacements for fluorescent lighting fixtures.
