CAPACITOR SELECTION

A capacitor is recommended for improve input stability performance during large load transients to prevent the

An additional 0.1uF ceramic capacitor can be placed on the AVIN rail to prevent excessive noise from coupling into

the device.

UTC UR5595 has been designed to be insensitive of output capacitor size or ESR (Equivalent Series Resistance).

As a general recommendation the output capacitor should be sized above 100μF with a low ESR for SSTL

applications with DDR-SDRAM. The value of ESR should be determined by the maximum current spikes expected

and the extent at which the output voltage is allowed to droop.

THERMAL DISSIPATION

The UR5595 will generate heat result from internal power dissipation when current flow working. The device might

be damaged any beyond maximum junction temperature rating. The maximum allowable internal temperature rise

materials, ambient air temperature and so on.
