HR1001B

Enhanced LLC Controller with

Adaptive Dead-Time Control

DESCRIPTION

FEATURES

The HR1001B is an enhanced LLC controller,

which provides new adaptive dead-time

adjustment (ADTA) and capacitive mode

protection (CMP) features.



Adaptive Dead-Time Adjustment

Capacitive Mode Protection

50% Duty Cycle, Variable Frequency

Control for Resonant Half-Bridge Converter

600V High-Side Gate Driver with Integrated

Bootstrap Diode with High dv/dt Immunity

High-Accuracy Oscillator

The adaptive dead-time adjustment inserts a

dead time between the two complimentary gate

outputs automatically.

keeping the outputs off while sensing the dv/dt

current of the half-bridge switching node. The

ADTA features easier design, lower EMI, and

higher efficiency.



This is ensured by



Operates up to 600kHz

Two-Level

Over-Current

Protection:

Frequency Shift and Latched Shutdown with

Programmable Duration Time

Latched Disable Input for Easy Protection

Remote On/Off Control and Brown-Out

Protection through the BO Pin

Programmable Burst Mode Operation at

Light Load

Non-Linear Soft Start for Monotonic Output

Voltage Rise

SOIC-16 Package



The HR1001B incorporates anti-capacitive

mode protection, which prevents potentially

destructive capacitive mode switching if the

output is shorted or has a severe overload.

This feature protects the MOSFET during

abnormal conditions, making the converter

robust.



The HR1001B has a programmable oscillator

that sets both the maximum and minimum

switching frequencies.

programmed maximum switching frequency

and decays until the control loop takes over to

prevent excessive inrush current.

APPLICATIONS

It starts up at a



LCD and PDP TVs

Desktop PCs and Servers

Telecom SMPS

AC/DC Adapter, Open-Frame SMPS

Video Game Consoles

Electronic Lighting Ballast

The HR1001B enters a controlled burst mode at

light load to minimize the power consumption

and tighten output regulation.

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

The HR1001B provides rich protection features,

including two-level OCP with external latch

shutdown, auto-recovery, brown in/out, CMP,

and OTP, improving converter design safety

with minimal extra components.
