High-Performance

Digital PFC+LLC Combo Controller

The Future of Analog IC Technology

PRELIMINARY SPECIFICATIONS SUBJECT TO CHANGE

FEATURES

DESCRIPTION

•

Meets EuP Lot 6 and COC Version 5 Tier 2

Specifications

The HR1200 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) Lot 6 and Code

of Conduct Version 5 Tier 2 specifications.

•

HV Current Source for Start-Up

Smart X-Cap Discharger when AC is

Removed

•

Standard I²C Interface

1K EEPROM to Store Parameters

User-Friendly GUI for Digital PFC

High Efficiency from Light Load to Full Load

by CCM/DCM Multi-Mode Control

High PF Due to Patented Input Capacitor

Current Compensation

The PFC of the HR1200 employs a patented

average current control scheme, which can

operate in CCM and DCM multi-mode

according to the instantaneous condition of the

input voltage and output load. The IC exhibits

excellent efficiency and high PF at light load.

When operating in CCM, the controller can be

used in applications up to 500W with minimal

board size limitations. The performance of the

PFC can be optimized by programming multiple

parameters through an I²C GUI. Programming

is completed either by the factory or by the

customer using a detailed user guide.

Open-Loop Protection

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 Fault

Two-Level Over-Current Protection (OCP)

Latch Shutdown Protection

UTE

The half-bridge LLC converter achieves high

efficiency with zero-voltage switching (ZVS).

The HR1200 implements an adaptive dead-time

adjustment (ADTA) function, so the LLC

converter can achieve easily ZVS from heavy

load to light load. In addition, the HR1200 can

prevent the LLC converter from operating in

capacitive mode, making it more robust and

easier to design.

•

Over-Temperature Protection (OTP)

Capacitance Mode Protection

The HR1200 integrates a high-voltage (HV)

current source inside the IC for start-up,

external circuit. When the AC input is removed,

the HV current source functions as an X-cap

discharger, eliminating the need for a resistor

for X-cap discharging. These features reduce

the size of the BOM list and power consumption

at no load.
