Notes:

1. Maximum practical power is the power the part can deliver when properly

mounted to a heat sink and a maximum heat sink temperature of 90 °C.

• LED street and area lighting

• Printer power supplies

• Audio ampliﬁer

Description

The 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. Figure 1 shows a

simpliﬁed schematic of a HiperLCS based power stage where the LLC

resonant inductor is integrated into the transformer.

The variable frequency controller provides high-efﬁciency by

switching the power MOSFETs at zero voltage (ZVS), eliminating

switching losses.
