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. 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. Exceeding these parameters may result in permanent damage to the product
