Product Description

The EVHR1203-Y-00A is a general-purpose evaluation board for the HR1203 for 240W PC and ATX power, adapters, all-in-one or gaming power and general AC/DC power supply applications.

The HR1203 integrates a digital PFC controller and a half-bridge resonant controller into a single chip. It uses very low power at no load or ultra-light load, making it compliant with Energy Using Product Directive (EuP)Lot6 and Code of Conduct Version 5 Tier 2 specifications.

The PFC of the HR1203 employs a patented average current control scheme, which can operate in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) according to the instantaneous condition of the input voltage and output load. The IC exhibits excellent efficiency and a high power factor (PF) at light load.

The half-bridge LLC converter achieves high efficiency with zero-voltage switching (ZVS). The HR1203 implements an adaptive dead-time adjustment (ADTA) function so the LLC converter can easily achieve ZVS from heavy load to light load. Additionally, the HR1203 can prevent the LLC converter from operating in capacitive mode, making it more robust and easier to design.

Typically, the EVHR1203-Y-00A is designed for PC and ATX power, adapters and gaming power applications with a 12V, 20A constant voltage output and 240W rated power from 90VAC to 265VAC and 50Hz/60Hz.

The EVHR1203-Y-00A has excellent efficiency and a high power factor for the entire load range. Full protection features include overload protection, short-circuit protection (SCP), over-voltage protection (OVP), and anti-capacitive mode protection. The EVHR1203-Y-00A also meets the Class C standard of IEC61000-3-2 and EN55022 standard.

Parametrics


High-Performance Digital PFC + LLC Combo Controller

The HR1203 is a high-performance controller that integrates an advanced, digital, PFC controller and a half-bridge, LLC resonant controller. The HR1203 requires low input power at no-load or ultra-light load, making it compliant with the Energy Using Product Directive (EuP) Lot 6 and Code of Conduct Version 5 Tier 2 specifications.

The PFC of the HR1203 employs a patented average current control scheme, which can operate both in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) according to the instantaneous condition of the input voltage and output load. The IC exhibits excellent efficiency and high power factor (PF) at light load. The performance of the PFC can be optimized by programming multiple parameters through an I2C GUI. Programming can be completed either by the factory or by the customer referring to a detailed user guide.

The half-bridge LLC resonant converter achieves high efficiency with zero-voltage switching (ZVS). The HR1203 implements an adaptive dead-time adjustment (ADTA) function to guarantee ZVS in different load conditions. Additionally, the HR1203 can prevent the LLC converter from operating in capacitive mode, making it more robust and easier to design.

The HR1203 integrates a high-voltage (HV) current source internally for start-up. When the AC input is removed, the HV current source also functions as an X-cap discharger. Such features are helpful to reduce related devices, thus reduce power consumption at no load.

In order to improve the noise immunity, HR1203 implements multiple programmable digital filters on critical signals.

Full protection features include thermal shutdown, open-loop protection (OLP), over-current protection (OCP), over-voltage protection (OVP), and brown-in/-out protection.
