POWER INTEGRATIONS LCS700HG Datasheet & Stock

HiperLCS™ is an integrated LLC power stage incorporating a multi-function controller, high-side and low-side gate drivers, plus two power MOSFETs in a half-bridge configuration. The variable frequency controller provides high-efficiency by switching the power MOSFETs at zero voltage (ZVS), eliminating switching losses. LLC half-bridge power stage incorporating controller, high and low-side gate drives and high-voltage power MOSFETs eliminates up to 30 external components. Programmable burst mode maintains regulation at no-load and improves light load efficiency. Single package designed for high-power and high-frequency reduces assembly cost and reduces PCB layout loop areas. Paired with HiperPFS PFC product gives complete, high efficiency, low part count PSU solutions. Applications includes high-efficiency power supplies (80 PLUS silver, gold and platinum), LCD TV power supplies, LED street and area lighting, printer power supplies and audio amplifier.
