DESCRIPTION

The LT®8356-1 is a DC/DC controller designed to drive

high current LEDs. The fixed frequency, current mode

architecture results in stable operation over a wide range

of supply and output voltages. A voltage feedback pin

serves as the input for several LED protection features

and makes it possible for the converter to operate as a

constant-voltage source. The LT8356-1 can implement

boost, boost-to-battery, buck-mode, SEPIC, and flyback

LED drivers.

The LT8356-1 senses output current at the high or low

side of the load. The product of CTRL and IADJ inputs

provides analog programming of the output current. The

PWM input and PWMTG high side PMOS driver provides

precision time-based LED dimming capability. When

driven by an external digital signal, the PWM input pro

vides LED dimming ratios of up to 20,000:1 at 100Hz.

When driven by a constant voltage, the PWM input selects

from one of 128 internally generated, precision, expo

nentially spaced dimming ratios ranging from 0.78% up

to 100%.
