PT4115E
50V/1.5A Step-down High Brightness
LED Driver
GENERAL DESCRIPTION
FEATURES
The PT4115E is a continuous conduction mode
inductive step-down converter, designed for driving
single or multiple series connected LED efficiently
from a voltage source higher than the total LED chain
voltage. The device operates from an input supply
between 6V and 50V and provides an externally
adjustable output current of up to 1.5A.
The PT4115E includes the power switch and a
high-side output current sensing circuit, which uses an
external resistor to set the nominal average output
current, and a dedicated DIM input accepts either a DC
voltage or a wide range of pulsed dimming. Applying a
voltage of 0.3V or lower to the DIM pin turns the
output off and switches the device into a low current
standby state.
The PT4115E is available in SOT89-5 package.
Simple low parts count
Wide input voltage range: 6V to 50V

DESCRIPTION
Switch Output. SW is the drain of the internal N-Ch MOSFET
switch.
Signal and power ground. Connect directly to ground plane.
Logic level dimming input. Drive DIM low to turn off the current
regulator. Drive DIM high to enable the current regulator.
Current sense input
Input Supply Pin. Must be locally bypassed.
Internally connected to GND. Mount on board for lower thermal
resistance.
