This board offers a 0.8 amp buck point-of-load switch-mode regulator.

N.B. THIS IS A Buck TOPOLOGY…..+Vin MUST ALWAYS BE HIGHER THAN Vout

 

Features:

  1. +3.5 to +18VDC input voltage range
  2. Output adjustable from -1.25 to -15VDC
  3. 150KHz switching freq.
  4. 0.8 amp output capability (with adequate heatsinking)
  5. Dimensions: approx. 38 x 18 x 16 mm (L x W x H).
  6. Ideal for use with solderless breadboard mounting.
  7. Is one of 3 options from us…Buck/ Boost/ Invert
  8. Add-on output filter also available to suit lower noise requirements.
  9. Shipped with snap-off pins unfitted…need soldering.
  10. Made in England.
