Description
The FAN5601 is an advanced third generation switched capaci-
tor step down DC/DC converter utilizing Fairchild’s proprietary
ScalarPump™ technology. This innovative architecture utilizes
scalar switch re-configuration and fractional switching tech-
niques to produce low output ripple, low ESR spikes and
improve efficiency over a wide load range.
The FAN5601 produces a fixed regulated output from 2.2V to
5V input voltage. Customized output voltages are available in
100mV increments from 1V to 1.8V. Contact marketing for cus-
tomized outputs.
In order to maximize efficiency, 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.
