ZXLD1374

Versatile LED driver increases

reliability of high brightness lamps

The ZXLD1374 is a high

accuracy 1.5A LED driver

that can be used as a

Buck converter

Boost converter

Buck-Boost converter.

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

The Diodes advantage

The ZXLD1374 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

LED currents resulting in

uniform brightness and

eliminates the need for

ballast resistors.

The ZXLD1374 switches

at frequencies up to

Multi-topology device

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

qp

1MHz, which allows the

use of small size external

components. This coupled

with small footprint

TSSOP-20EP reduces the

required PCB area.

Circuit functions
