Description
The FAN5601 is an advanced third generation switched
capacitor step down DC/DC converter utilizing Fairchild’s
proprietary ScalarPump technology. This innovative archi-
tecture utilizes scalar switch re-conguration and fractional
switching techniques to produce low output ripple, low ESR
spikes and improve efciency over a wide load range.
The FAN5601 produces a xed regulated output from 2.2V
to 5V input voltage. Customized output voltages are avail-
able in 100mV increments from 1V to 1.8V. Contact market-
ing for customized outputs.
In order to maximize efciency, the FAN5601 achieves
regulation by skipping pulses. Depending upon load current,
the size of the switches is scaled dynamically, consequently,
current spikes and EMI are minimized. An internal soft start
circuitry prevents excessive current drawn from the supply.
The device is internally protected against short circuit and
over temperature conditions.
The FAN5601 is available in 6-lead 3x3mm MLP and 8-lead
MSOP packages.
