ZXLD1370

Versatile LED driver increases

reliability of high brightness lamps

Description

The ZXLD1370 is a high

accuracy LED driver controller;

the LED load current that can

be delivered is dependent on

the external MOSFET.

It can be used as a

It can be used as a

Buck converter

Boost converter

Buck-Boost converter.

It is Diodes’ first LED driver to

offer this functionality.

The device can drive up to

The Diodes advantage

The ZXLD1370 provide simple high reliability solution for driving

multiple extremely high brightness LEDs in multiple topologies

High accuracy LED control: 1% reference tolerance

Better brightness control and matching between lamps

Multi-topology device

The device can drive up to

16 LEDs in series from a

voltage source of 6.5V to

60V. Series connection of

the LED provides identical LED

currents resulting in uniform

brightness and eliminates

the need for ballast resistors.

1 device can be used in buck lighting, boost light and buck-boost

lighting apps

LED thermal management via external thermistor

Improves reliability of LED lamps

Separate 1000:1 PWM dimming capability

Improves dynamic range of dimming at lower light levels

Switching frequency up to 1MHz

Reduces value of inductor reducing size of solution

The ZXLD1370 switches at

frequencies up to 1MHz, which

allows the use of small size

external components, hence

minimizing the required

PCB area.

A 1.5A LED driver converter is

Circuit functions

Buck driving of 3W and

Boost driving of 3W

Reduces value of inductor reducing size of solution

Two- pin diagnostic feedback pins

Reports back to system the state of LED driver and load can be used

to increase reliability of overall system

A 1.5A LED driver converter is

expected to release in June

2010.
