8.2 Typical Application

This design example describes the HPA341 EVM design and outlines the design steps required to design a 300-W LLC resonant half-bridge converter, which provides a regulated output voltage nominally at 12 V at maximum 300 W of load power, with reinforced isolation of AC-DC off-line applications between the primary and the secondary, operating from a DC source of 390 V.
