Programmable quad output PMIC for FPGA, SoC, DSP power

New Products |
By eeNews Europe

This controller is a single input, quad output, step-down switching regulator controller with integrated gate drivers and dual LDO outputs. It can monitor and dynamically control and configure the power system through an I²C interface. Five configurable GPIOs allow for fast system integration for fault reporting and status or for sequencing control.

The XR77129 can be configured to power nearly any FPGA, SOC or DSP system through the use of Exar’s design tool, PowerArchitect and programmed through an I²C based SMBus compliant serial interface. PowerArchitect 5.2 has been upgraded to support the additional capabilities of the XR77129 including output voltage ranges beyond the native 0.6V to 5.5V with the use of external feedback resistors. The XR77129 wide input voltage range, low quiescent current of 450 µA (standby) and 4 mA (operating) make it a suitable choice for a wide range of systems including 18V to 36 VDC, 24 VDC or rectified AC systems used in industrial automation and embedded applications.

In a 7mm × 7mm TQFN it is priced at $9.95 (1000).
