The UTC
L5100
is a STEP-UP DC/DC Converter and
designed for driving white LEDs with a constant current. It
can drive several LEDs in series by a Li-Ion cell. UTC
L5100
switches at a high frequency 1.2MHz, so it can allowing the
use of tiny external components. The output capacitor can be
as small as 0.22μF, saving space and cost compare with
alternative other solutions. The low 95mV feedback voltage
minimizes power loss in the current setting resistor can have
better efficiency.
