Power Integrations, a provider of high-voltage integrated circuits for energy-efficient power conversion, has announced a two-fold increase in power output for its HiperLCS-2 chipset.
The new device features advanced half-bridge switch technology in a compact, thermally efficient package, delivering up to 1650 W of continuous output power with efficiency exceeding 98%.
Targeting applications such as e-scooter chargers and industrial power supplies, it supports high levels of integration to reduce enclosure size and eliminate the need for air vents or fans — enhancing system reliability and environmental resistance.
The HiperLCS-2 family reduces component count and board area by 30 to 60% in half-bridge LLC resonant power converters rated at 50 W and above. Continuous power output now exceeds 1.6 kW, with support for peak loads of up to 2.5 kW, enabled by a new POWeDIP package.
This package incorporates a thermally conductive, electrically insulating ceramic pad that attaches to flat heat-sinking surfaces and provides sufficient creepage clearance to the pins, achieving thermal performance under 1° C / W.
On the primary side, the HiperLCS2-HB integrates 600 V FREDFETs in a half-bridge configuration and includes self-bias and start-up control, eliminating the need for an external bias supply. The companion HiperLCS2-SR IC features a secondary-side master controller with optimized synchronous rectification (SR) for reduced output losses.
A built-in FluxLink isolator provides high-speed, robust feedback to the primary-side controller, removing the need for optocouplers. The IC also manages multi-mode burst operation for improved light and no-load efficiency, suppresses audible noise, and minimizes output ripple. Comprehensive fault protection is integrated to support high system reliability.
