The MCP1623 boost converter.

They recommend a 4.7µH inductor, and they support boosting from 3.4V to 5V. At low currents, the efficiency can drop to 0.6.

TI Application Note SLVA372D gives inductor ripple current as T*Vin*D/L. That works out to

> 3.4V * 0.6 / (270kHz * 4.7µH)
680/423, approx. 1.607565 ampere (current)

which is WAY above the converter's switching current.

And yet, it works.

What is wrong with my calculations?
