HR1001A

Enhanced LLC Controller with

Adaptive Dead-Time Control

The Future of Analog IC Technology

DESCRIPTION

HR1001A is the OCP auto-recovery version of

HR1001B.

FEATURES

•

Two-Level

Over-Current

Protection:

Frequency Shift and Auto-Recovery Mode

with Programmable Duration Time

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

HR1001A is an enhanced LLC controller, which

provides new features of adaptive dead-time

adjustment (ADTA) and capacitive mode

protection (CMP).

•

The adaptive dead-time adjustment inserts a

dead time between the two complimentary gate

•

outputs automatically.

This is ensured by

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.

•

Operates up to 600kHz

Latched Disable Input for Easy Protection

Remote On/Off Control and Brown-Out

Protection through BO

Programmable Burst Mode Operation at

Light Load

Non-Linear Soft Start for Monotonic Output

Voltage Rise

SOIC-16 Package

HR1001A 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.

APPLICATIONS

HR1001A has a programmable oscillator that

sets both the maximum and minimum switching

frequencies. It starts up at a programmed

maximum switching frequency and decays until

the control loop takes over to prevent excessive

inrush current.

•

LCD and PDP TVs

Desktop PCs and Servers

Telecom SMPS

AC/DC Adapter, Open-Frame SMPS

Video Game Consoles

Electronic Lighting Ballast

HR1001A 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 RoS directive.

HR1001A provides rich protection features,

including two-level OCP, auto—recovery,

external latch shutdown, brown in/out, CMP,

and OTP, improving converter design safety

with minimal extra components.
