PSU NCP3063 0.1 amp inverting regulator

This board offers a 0.1 amp boost-invert point-of-load switch-mode regulator.

N.B. THIS IS A BOOST TOPOLOGY…..+Vin MUST ALWAYS BE LOWER THAN -Vout

ALSO THE MAGNITUDE OF Vin+Vout MUST NEVER EXCEED 40VDC

Features:

1. +5VDC input voltage
2. Output adjustable from -1.25 to -16.5VDC
3. 150KHz switching freq.
4. 0.1 amp output capability (with adequate heatsinking,

and possibly more when using a higher input voltage)

1. Dimensions: approx. 38 x 18 x 16 mm (L x W x H).
2. Ideal for use with solderless breadboard mounting.
3. Is one of 3 options from us…Buck/ Boost/ Invert
4. Add-on output filter also available to suit lower noise requirements.
5. Shipped with snap-off pins unfitted…need soldering.
6. Made in England.
