Power Integrations' HiperLCS is an integrated LLC power stage incorporating a multi-function controller, high and low-side gate drivers, and two power MOSFETs in a half-bridge configuration. It eliminates up to 30 external components and reduces assembly cost and PCB layout loop areas. The maximum operating frequency of 1 MHz dramatically reduces magnetics size and allows the use of SMD ceramic output capacitors. The HiperLCS has programmable dead-time for optimized design and improved efficiency; programmable burst mode, which maintains regulation at no-load and improves light load efficiency; and programmable soft-start time and delay before soft-start.
