Controllers power next-gen enterprise networking equipment

Many high performance FPGAs require a third power supply commonly referred to as the auxiliary rail (AUX). The AUX rail is often used to power internal clocks, phase-lock loops, peripheral input/output devices and transceivers in FPGA applications. These are critical rails that require tight tolerances and low jitter and ripple on the output voltages.

The ZSPM1505 and ZSPM1506 are pre-configured to provide customers with a fast time-to-market and easy-to-design solution for high-performance, digitally controlled power supplies with one of ZMDI’s integrated MOSFET power stage DrMOS products: the ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. The ZSPM15xx family of digital controllers features a flexible design that allows users to easily select the over-current protection limit, output voltage rise time and control loop compensation via two external resistors to achieve the highest performance in their application.

The ZSPM1505 is preconfigured for a power stage output of 1.8V and is capable of supporting loads of up to 30A. The ZSPM1506 can support loads of up to 25A at 2.0V. ZMDI provides BOMs and circuit board layouts to improve customer design cycles, reduce external component costs and minimise application footprint size.

“Many of the high performance FPGAs in enterprise networking and storage equipment require tightly regulated supply voltages to ensure the FPGA functions at its optimum performance,” said Hensen Wong, Product Marketing Manager, Power Management Division, ZMDI. “ZMDI is able to provide customers with a fast time-to-market with a highly accurate power solution with very low jitter and ripple.”
