DESCRIPTION
The SP6680
is a charge pump ideal for converting a +3.6V Li-Ion battery input to a +5.0V
regulated output. An input voltage range of +2.7V to +6.3V is converted to a regulated output
of 5.8V. The SP6680
device will operate at three different switching frequencies correspond-
ing to three different output resistances and load current ranges. An external 32.768kHz
nominal clock signal is used to produce three synchronized pump frequencies through the use
an internal phase lock loop to drive the charge pump. Two control inputs can adjust the internal
pump frequency on the fly to 8.192kHz (f
/ 4), 32.768kHz (f
x 1), or 262.14kHz (f
x 8). The charge pump configuration dynamically changes to optimize power efficiency. At
low input voltages the charge pump doubles the input while at higher inputs the output is 1.5
times the input. The SP6680 can deliver high power efficiencies up to 96% with low quiescent
currents from 75
