Overview
Introduction
The EVKT-1203 is an evaluation kit for the HR1203. A 240W evaluation board is designed with a high
power factor (PF) at light load (>0.95 at 20% load). The unique benefits for the board are its very low no-
load power consumption (<150mW) and very high light-load efficiency (>90% at 10% load), which meets
Energy using Product Directive (EuP) Lot 6 and Code of Conduct Version 5 Tier 2.
These features are suitable for applications including PCs, ATX power, notebook adapters, and gaming
and TV power supplies. With the programming communication interface and GUI software, circuit
configurations of the digital PFC part can be easily customized, greatly increasing design flexibility.
