Non-Isolated LED Lighting Applications
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
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.
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.
