LT3966

I C Programmable Quad

Monolithic Boost LED Driver

FEATURES

DESCRIPTION

The LT^®3966 is an I C programmable monolithic boost

Four Independent DC/DC Channels

I C Programmable

LED driver with four independent channels. Each chan-

nel provides a 60V current mode boost converter with

an internal 1.6A DMOS power switch, as well as inter-

8192:1 True Color PWM™ Dimming

8-Bit Analog Dimming Pin Scaled by DAC

11-Channel, 8-Bit ADC with 2 External Inputs

nal and external analog and PWM dimming features. I C

1.6A, 60V Internal DMOS Switches

Input Voltage: 3V to 60V

programmable features include a 13-bit (8192:1) digital

PWM generator, 8-bit analog dimming DAC, and flexible

fault reporting and handling.

Output Voltage and Current Monitoring to 60V

High Side PMOS Disconnect and PWM Switch Driver

An onboard 8-bit ADC allows measurement of each

channel’s output voltage and output current, as well

as chip input voltage and two external measurements.

In addition, independent shutdown and standby con-

trol of each channel provides flexible solutions for

multitopology applications.

Adjustable Frequency: 300kHz to 4MHz with Optional

Frequency Synchronization

Thermally Enhanced 6mm × 6mm 40-Lead QFN Package

AEC-Q100 Qualification in Progress

APPLICATIONS

The LT3966 is available in a thermally enhanced 6mm ×

6mm 40-Lead QFN package.
