Question Do I need to connect an external diode between SW to PGND? Answer ADP2441 is designed to reduce complexity of power supply design. It has
internal high side and low side FETS. It is not required…
Question Which of the following ADP2441 pins can be left floating?
PGOOD
FREQ
SS/TRK Answer The PGOOD pin can be left floating if not used.
The ADP2441 requires frequency resistor to be set in…
Q
What is the minimum ON time of ADP2441?
A
The maximum operating frequency is limited by the minimum on-time and the required duty cycle. ADP2441 has minimum on time of 50ns. Low minimum on-time…
Question The ADP2441 has a peak current limit of 1.6A. Does this mean I can operate
the ADP2441 at 1.6A Load current? Answer No, peak inductor current does not mean the average load current. The average…
Question Does ADP2441 support a precharge startup? Answer Yes, ADP2441 supports a precharged condition. If the output voltage is
precharged prior to enabling, the control logic prevents inductor current…
Question What is VCC pin in the ADP2441? Answer VCC pin is the output of the internal low dropout regulator. Internal regulator
supplies power for the internal controller and driver circuitry. A 1 µF…
Question What are the factors I should keep in mind to improve the efficiency of my
design? Answer The ADP2441 has internal FETS that are optimized for high efficiency. ADP2441
offers peak
efficiency…
Question In some of our projects, we are using ADP2441ACPZ-R7.
I want to calculate variation of power dissipation for two situations. But when
I use equations in datasheet of the product, I noticed…
