Nijkerk Electronics, Leading value added distributor of electronic components

Nijkerk Electronics was founded in Amsterdam in 1959 as a distributor of electronic components with subsidiaries in The Netherlands and Belgium. As one of the last independent companies of its kind Nijkerk Electronics succeeded in developing herself as one of the most im portant suppliers of semiconductors, passive com ponents, opto electro nics and modules. During the past 5 decades Nijkerk Electronics has invested strategically in state-of-the-art software and computer technology, as well as in-house engineering know- how, to optimize its role as a leading value added distributor of electronic components.

Dear Visitor,

Lowest Component Count, Off-Line Switcher IC for
Non-Isolated LED Lighting Applications

The LYTSwitch-0 family is specifically designed for low cost LED
bulb and T8 tube applications. LYTSwitch-0 devices monolithically
integrate a 700 V power MOSFET, oscillator, ON/OFF controller
scheme, EMI reduction and control functions including
cycle-by-cycle current limit and thermal shutdown circuitry into
one IC.

Product Highlights


The LYTSwitch-0 family enables low component-count,
non-isolated switching topologies for highly cost
competitive LED lighting applications. 66 kHz operation
together with frequency jittering insures a very low EMI
filter cost. Start-up and operating power are derived
directly from the voltage on the DRAIN pin, eliminating
the need for a bias supply and associated circuitry.

Power Factor Correction

The LYTSwitch-0 family enables designs that easily meet
European and North American standards for PFC in
consumer lighting applications.

Tight CC Performance

Accurate CC with tight line and load regulation that is
stable over a wide temperature range makes the
LYTSwitch-0 ideal for LED lighting applications.

Comprehensive Protection

Integrated auto-restart for short-circuit, open-circuit and
open loop faults as well as a hysteretic over temperature
protection feature (135 °C) provide extensive protection
at no additional cost.

Supports Different LED Applications

Buck, buck-boost non-isolated flyback, and boost
architectures are all supported by the LYTSwitch-0 family.
The 700 V switching power MOSFET supports an input
voltage range of 85 VAC to 308 VAC.
