HR1201

High-Performance Digital PFC +

Analog LLC Combo Controller with

Standby Power Input to VCC

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The HR1201 is a high-performance controller

that integrates an advanced digital PFC

controller and a half-bridge LLC resonant

controller. The HR1201 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

Standard I²C Interface



1k EEPROM to Store Parameters

User-Friendly GUI for Digital PFC

VCC Supplied by External DC Input from

Additional Isolated Power Source

The PFC of the HR1201 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 a high power

factor (PF) at light load. In CCM, the HR1201

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 can be completed either by the

factory or by the customer with a detailed user

guide.



Variable Frequency Control for Flat

Efficiency and PF Curve



High PF Due to Patented Input Capacitor

Current Compensation



Programmable Frequency Jittering

Programmable Brown-In and Brown-Out

Programmable Soft Start (SS)

Cycle-by-Cycle Current Limit

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 System Fault

Two-Level Over-Current Protection (OCP)

Latch Shutdown Protection



The half-bridge LLC resonant converter

achieves high efficiency with zero-voltage

switching (ZVS). The HR1201 implements an

adaptive dead-time adjustment (ADTA) function

to guarantee ZVS in different load conditions.

Additionally, the HR1201 can prevent the LLC

converter from operating in capacitive mode,

making it more robust and easier to design.



Over-Temperature Protection (OTP)

Capacitive Mode Protection

APPLICATIONS

Full protection features include thermal

shutdown, open-loop protection (OLP), over-

The HR1201 is suitable for standby power

applications. The HR1201 is available in a

SOIC-28 package.

MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For
