Exceeding these parameters may result in permanent damage to the product
Picor’s QPO-1 output ripple attenuator
System-in-a-Package (SiP) provides active
filtering to achieve greater than 20 dB
attenuation of periodic and random deviation
(PARD) over the frequency range of
50Hz to 500kHz.
The QPO-1 operates over a voltage range
of 3 to 30Vdc and is compatible with most
switching power supplies and converters.
The load is regulated by using remote
sensing or a reference type trim adjustment
feature as is commonly found on most
power supplies.

Part Numbering
The QPO-1’s closed loop architecture
greatly improves load transient response
while ensuring steady-state precise point of
load voltage regulation. The QPO-1 is
available in surface mountable Land Grid
and Ball Grid Array terminations.
