FP6700
Universal High
Brightness LED Driver
Description
The FP6700 is a PWM high-efficiency LED driver
control IC. It allows efficient operation of High
Brightness (HB) LEDs from voltage sources ranging
from 8VDC up to 450VDC. The FP6700 controls an
internal MOSFET at fixed switching frequency up to
300 kHz. The frequency can be programmed using a
single resistor. The LED string is driven at constant
current rather than constant voltage, thus providing
constant light output and enhanced reliability. The
output current can be programmed between a few
milliamps and up to more than 1.0A.
FP6700 uses a rugged high voltage junction isolated
process that can withstand an input voltage surge of
up to 450V. Output current to an LED string can be
programmed to any value between zero and its
maximum value by applying an external control
voltage at the linear dimming control input of the
FP6700. The FP6700 provides a low-frequency
PWM dimming input that can accept an external
control signal with a duty ratio of 0-100% and a
frequency of up to a few kilohertz.
