HR1203  
High-Performance  
Digital PFC + LLC Combo Controller with  
Programmable Noise Suppression Filter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
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.  
General System Features  
Meets EuP Lot 6 and COC Version 5 Tier 2  
Specifications  
HV Current Source for Start-Up  
Smart X-Cap Discharger  
Standard I2C Interface  
1k EEPROM to Store Parameters  
User-Friendly GUI for Digital PFC  
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.  
PFC Controller  
High Efficiency from Light Load to Full Load  
by CCM/DCM Multi-Mode Control  
High PF Due to Patented Input Capacitor  
Current Compensation  
Programmable Filter for Noise Suppression  
Programmable Frequency Jittering  
Programmable Brown-In and Brown-Out  
Programmable Soft Start (SS)  
Cycle-by-Cycle Current Limit  
Open-Loop Protection (OLP)  
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.  
LLC Controller  
600V High-Side Gate Driver with Integrated  
Bootstrap Diode and High dV/dt Immunity  
Adaptive Dead-Time Adjustment of HB LLC  
with Minimum and Maximum Limit  
Burst Mode Switching  
Safe Start-Up in Case of System Fault  
Two-Level Over-Current Protection (OCP)  
Latch Shutdown Protection  
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.  
Over-Temperature Protection (OTP)  
Capacitive Mode Protection  
APPLICATIONS  
Notebook Adapters  
In order to improve the noise immunity, HR1203  
implements multiple programmable digital filters  
on critical signals.  
All-in-One or Gaming Power Supply  
Desktop PC and ATX Power  
General AC/DC Power Supply up to 600W  
OLED and Large Format LCD TV Power  
Supply  
Full protection features include thermal  
shutdown, open-loop protection (OLP), over-  
current  
protection  
(OCP),  
over-voltage
