Where R
1
is the resistor connected between the output voltage and the feedback pin, while R
2
is between the
feedback pin and ground.
ZERO LOAD
Due to the fact that the internal power is a PDMOS, no boostrap capacitor is required and so, the device works prop-
erly also with no load at the output. In this condition it works in burst mode, with random repetition rate of the burst.
APPLICATION CIRCUIT
In figure 6 is shown the demo board application circuit, where the input supply voltage, V
cc
, can range from 4.4V
to 25V due to the rated voltage of the input capacitor and the output voltage is adjustable from 1.235V to V
cc
.
