Frequently Asked Questions

How is the output voltage selected for this converter?

The VSEL input allows selection between two operating ranges: 3.13V–3.54V or 5.23V–5.85V.

What component controls the maximum current limit (I_LIM)?

The I_LIM is set by an external 1% accurate resistor R connected between pin 7 and pin 6.

Does it support synchronization with an external clock?

Yes, the device synchronizes to an external high-frequency clock using the SYNC input up to -13- MHz.

What is the typical efficiency range of the DC/DC converter?

The typical efficiency ranges from 90% to 95%, depending on the operating voltage and load current.
