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

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).
