Trim output voltage

up 1 diode drop

CTRL

Add a blocking diode to Vout

if current can flow back-

wards into the output, as this

can damage the converter

when it is powered down.

The diode can either be fitted

across the device if the

source is low impedance or

fitted in series with the out-

put (recommended).
