Single-package, 5-output voltage regulator feeds FPGAs, ASICs
The device is aimed at current and future applications in high density ASIC and FPGA. Additional applications comprise CPU multi-rail systems, embedded computing systems, and communication and storage systems.
The IRPS5401 forms a key part of the UltraZed System on a Module (SOM) from Avnet. The compact package size combined with PMBus communication for real-time monitoring and control provides the optimized power management solution that the UltraZed requires. “With the integration level and excellent power density of the IRPS5401, we were able to implement two IRPS5401 devices onto our full-featured UltraZed SOM,” said Chris Ammann, Global Technical Marketing Engineer for Power at Avnet. This gives us 10 rails that can be fully monitored and controlled with software, while maintaining a business card size footprint for the SOM.”
The IRPS5401 is designed for single rail operation ranging from 5V to 12V, where most PMICs are only 5V. It has one 500 mA LDO output, and four configurable switching regulator outputs, two at 2A, and two at 4A. The outputs of the IRPS5401 can be used to provide the typical rails required for core, memory, and I/O voltages. The voltage output range is between 0.5 V and 3.6 V for regulators A to D, and between 0.25 V and 5.1 V for the LDO.
Switching regulator A can output up to 50A if combined with an external power stage. Switching regulators C and D can be combined to deliver 8A in a low ripple, dual-phase configuration. All outputs are well within the power requirements of most FPGAs and ASICs ranging between 10W to 50W, including integrated voltage sequencing. Industry standard PMBus commands provide an easy-to-use interface for status and telemetry, and PMBus can be used to configure the output voltages in 5 mV steps.
