The Power Integrations LYTSwitch™-0 family of low-power AC-DC converters is specifically designed for low cost LED lamp replacement applications. The devices integrate a high voltage power MOSFET with the required control circuitry to implement a compact and efficient solution suitable for a variety of converter topologies. The LYT0004, LYT005 and LYT006 types include an auto restart function which operates after a fault or overload condition has occurred. Package options include both through-hole and surface-mount devices to suit different manufacturing requirements.

• High power factor meeting EU and USA requirements
• Very low component count
• 66 kHz operation with frequency jitter reduces EMI
• No bias supply or transformer required
• Good constant current regulation
• Accurate current limit with tight line and load regulation
• Protection for over-temperature, short-circuit, open-circuit and open loop faults
• Suitable for flyback, buck, buck-boost and boost architectures
