The ZSPM1503 from ZMDI is a single-phase, true-digital power solution that has been optimised to power field programmable gate arrays (FPGAs) in telecommunication, data communication and networking applications. The IC has the ability to regulate the output voltage within a tight tolerance of ±1% and minimise output ripple voltage to 5 mV peak-to-peak or better, which is typically needed to power the core voltage for FPGAs with a 1,2 V supply.
The ZSPM15xx family features ZMDI’s Tru-sample Technology, which reduces phase lag caused by sampling delays, minimises noise sensitivity and improves transient performance. This enables the acquisition of fast, accurate and continuous information about the output voltage so that the device can react instantaneously to any changes in the output voltage.
The ZSPM1503 permits users to easily select the over-current protection limit, output voltage rise time and control loop compensation via two external resistors. It is capable of supporting loads up to 35 A with the popular bus voltage of 1,2 V.
