Charge Pump White LED Driver IC
TK65700L
DESCRIPTION
The TK65700L is a charge pump white LED driver IC. This
device has been optimized for battery controlled systems
where power consumption and size, high efficiency are
primary concerns. With a switching frequency of 1.2MHz,
the operation of the IC should not disturb 455kHz IF
subsystems.
