Digital power controller with ‘Tru-sample Technology’ runs 35A to FPGAs

New Products |
By eeNews Europe

ZSPM1503 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 1.2V 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. Tru-sample Technology enables the devices family to acquire fast, accurate and continuous information about the output voltage so that the ZSPM15xx can react very quickly to any changes. The ZSPM1503 is pre-configured to provide an easy-to-design digitally controlled power solution with one of ZMDI’s integrated MOSFET power-stage DrMOS products: the ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. The ZSPM1503 permits users to easily select the over-current protection limit, output voltage rise time and control loop compensation via two external resistors.

The ZSPM1503 is capable of supporting loads up to 35A with the popular bus voltage of 1.2V. ZMDI also provides bills-of-materials (BOMs) and circuit board layouts to improve design cycles, reduce external component cost and minimise application footprint size.

The ZSPM1503 is priced at €0.87 or $1.22 (1000).
