FEATURES

DESCRIPTION

•

LLC Resonant Switching Driver Controller for

The TPS92023 is a high-performance resonant-

Multi-String LED Lighting Applications

switching LED driver controller. It is designed for use

•

Half-Bridge Topology

in higher power LED lighting systems. The TPS92023

•

Fixed or Variable Switching Frequency Control

uses resonant switching in an LLC topology to

achieve a very high efficiency compared to traditional

•

Programmable Soft-Start Time

half-bridge converters.

•

Programmable Dead Time for Best Efficiency

The programmable dead time enables zero-voltage

•

Easy ON/OFF Control

switching

with

minimum

magnetizing

current,

•

Overcurrent Protection

maximizing system efficiency across a variety of

•

Over-Temperature Protection

applications.

•

Bias Voltage UVLO and OVP

The

TPS92023

can

operate

in

two

switching

•

Integrated Gate Driver With 0.4-A Source and

frequency modes. Fixed frequency allows for simple

design when the load current is constant while

0.8-A Sink Capability

variable switching allows for optimal closed-loop

•

Operating Temperature Range: –40°C to 125°C

control for loads with varying currents. The internal

•

SOIC 8-Pin Package

oscillator supports the switching frequencies from

30 kHz to 380 kHz. This high-accuracy oscillator

APPLICATIONS

realizes the minimum switching frequency limiting

with 4% tolerance, allowing the designer to avoid

•

Commercial / Industrial LED Lighting Drivers

over-design of the power stage and, thus, further

•

High Bay LED Lighting

reducing overall system cost.

•

Low Bay LED Lighting

•

Street LED Lighting

•

Area LED Lighting

•

Stadium LED Lighting

•

LED Wall Washing

•

LED DTV and Monitor Back-lighting
