HR1213  
Multi-Mode PFC and Current Mode LLC  
Combo Controller Supporting both AC and  
DC Inputs with Configurable Bias Options  
DESCRIPTION  
FEATURES  
The HR1213 is a multi-mode PFC and current  
mode LLC combo controller that can be  
configured via the UART interface. Power-  
saving technology helps the device optimize  
efficiency across the full operating range.  
•
General System Features:  
o High-Voltage Current Source for Start-  
Up  
o UART Interface for Configurations  
o User-Friendly GUI  
o Available in SOIC-20 and TSSOP-20  
Packages  
PFC Controller:  
The PFC controller employs a patented, digital  
average current control scheme to achieve  
hybrid continuous conduction mode (CCM) and  
•
o CCM/DCM Multi-Mode PFC Control with  
High Efficiency across All Loads  
o Operating Frequency Up to 250kHz  
o High PF due to Input Capacitor Current  
Compensation  
o Configurable Frequency Jittering  
o Configurable Soft Start and Burst On  
o Configurable AC Input Brown-In/Out  
o Cycle-by-Cycle Current Limiting  
o OLP, OVP  
discontinuous

mode  
(DCM)  
operation. Under heavy loads, CCM reduces the  
peak MOSFET current so the controller can be  
used across a wider load range. Under light  
loads, DCM reduces the switching frequency for  
better efficiency. Burst mode has configurable,  
digital soft switching to improve both light-load  
efficiency and audible noise.  
Current mode control is implemented in the LLC  
stage to achieve good stability and fast  
response. Three operation modes are  
implemented based on the different load  
conditions: steady state, skip, and burst mode.  
This allows different load conditions to be  
independently optimized for efficiency. At light  
loads, digital, frequency-controlled burst mode is  
applied to reduce both switching power loss and  
audible noise. Adaptive dead-time adjustment  
(ADTA) and capacitive mode protection (CMP) is  
also applied to guarantee zero-voltage switching  
(ZVS) without capacitive mode operation.  
•
LLC Controller:  
o 600V HS Gate Driver with Bootstrap  
Diode and High dV/dt Immunity  
o Current Mode Control  
o Up to 500kHz in Steady State  
o Adaptive Dead-Time Adjustment with  
Minimum and Maximum Limit  
o Burst/Skip Mode Switching under Light  
Loads  
o Configurable Burst Frequency with Low  
Audible Noise  
o Configurable Soft Start  
o Configurable DC Input Brown-In/Out  
o Capacitive Mode Protection  
o OCP and OPP with Auto-Restart or  
Latch-Off Mode  
The HR1213 has an internal, high-voltage (HV)  
current source for start-up, meaning that a  
traditional start-up resistor or external circuit is  
not required. An external DC source can provide  
a supply for VCC.  
o Configurable Protections on the SO Pin  
APPLICATIONS  
Protections include thermal shutdown (TSD),  
PFC open-loop protection (OLP), over-voltage  
protection (OVP), over-current limit (OCL) and  
LLC over-current protection (OCP), SO pin  
protection, and over-power protection (OPP).
