HR1000A

Resonant Half-Bridge Controller

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The HR1000A is a controller designed specifically

for the resonant half-bridge topology. It provides

•

50% Duty Cycle, Variable Frequency

Control For Resonant Half-Bridge Converter

600V High-Side Gate Driver with Integrated

Bootstrap Diode and High dV/dt Immunity

1.5A/2A Source/Sink Capability for Both

High-Side and Low-Side Gate Drivers

High-Accuracy Oscillator

two

drive-signal

channels

that

output

complementary signals at a 50% duty cycle. An

internal fixed dead-time of 350ns between the

two complementary gate signals guarantees

zero-voltage switching during the transient and

enables high-frequency operation.

•

Operates at up to 600kHz

Two-Level

Over-Current

Protection:

The integrated bootstrap diode simplifies the

external driving circuit for the high-side switch. It

can withstand up to 600V with immunity against

high dV/dt noise.

Frequency-Shift and Latched Shutdown with

Programmable Duration Time

Remote ON/OFF Control and Brown-Out

Protection through the BO Pin

Latched-Disable Input for Easy Protections

Implementation

Interfaces with PFC Controller

Programmable Burst-Mode Operation at

Light-Load

•

Modulating the switching frequency regulates the

topology output voltage.

programmable

oscillator can set both the maximum and

minimum switching frequencies.

•

The IC starts up at the programmed maximum

switching frequency and gradually slows until the

control loop takes over to prevent excessive

inrush current

•

Non-Linear Soft-Start for Monotonic Output

Voltage Rise

SO-16 package

The IC can be forced to enter a controlled burst-

mode operation at light-load to minimize the

power consumption and tighten output regulation.

APPLICATIONS

•

LCD and PDP TVs

Desktop PCs and Servers

Telecom SMPS

AC-DC Adapter, Open-Frame SMPS

Video Game Consoles

Electronic Lighting Ballast

Protections features—including latched shutdown,

auto-recovery, brown-out protection, and over-

temperature

protection—improve

converter

design safety without engendering additional

circuit complexity.

The IC provide 1.5A/2A source/sink capability for

both high-side and low-side gate drivers.
