Description
The
YB1509
is
a
high-power
boost
converter. An adjustable current limit, wide
range of input voltage, and up to 40V of
switch voltage are designed to drive white
LEDs back-lighting for large LCD panel. It
can drive up to 10 LEDs in series or 18
LEDs in parallel/series configuration.
The wide application VIN range makes
YB1509 suitable for many types of battery
applications such as Li-ions, Alkaline, or
Sealed Lead Acid batteries. The adjustable
inductor current optimizes the performance
for different output drive capability by an
external resistor.
The LED current is set by a resistor
connected to FB pin. The On/Of duty with
clock frequency from 1K to 100KHz at EN
pin can control the LED brightness
