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.

Features and Benefits
The evaluation board is mainly designed to demonstrate the capabilities of MPS’s highly integrated HR1203 controller. The HR1203 is a high-performance combo controller that integrates an advanced digital PFC controller and a half-bridge LLC resonant controller.
The PFC part employs a patented average current control scheme, and can switch automatically between continuous conduction mode (CCM) and discontinuous conduction mode (DCM), according to the instantaneous condition of the input voltage and output load. With this feature, the IC exhibits excellent efficiency and high PF at light load. The LLC part implements an adaptive dead-time adjustment (ADTA) function to guarantee zero-voltage switching (ZVS) in different load conditions. In addition, a high-voltage (HV) current source is integrated internally for start-up and X-cap discharge, which helps reduce power consumption at no load.
Use the USB isolator when in online mode with AC input.
Make sure both the communication interface and EVB board are reset every time before
restarting the GUI.
