Power Integrations introduced HiperLCS, a family of high-voltage LLC power supply ICs that incorporate the controller, high- and low-side drivers, and both MOSFETs into a single low-cost package. Highly integrated HiperLCS ICs offer the flexibility to optimize designs either for high efficiency, with a maximum efficiency of better than 97%, or for size, by leveraging high-frequency operation (up to 1 MHz) to minimize transformer size and output capacitor footprint.
The high switching frequency of HiperLCS devices allows designers to use low-cost SMD ceramic capacitors in the output loop instead of bulky, unreliable electrolytic capacitors, and reduces the size of the magnetics required. It also delivers excellent transformer utilization, with a peak switching frequency of 1 MHz. Power Integrations’ new thermally-efficient, low-profile eSIP-16C package further contributes to space savings and reduces heat sink size.
