Exar Delivers XRP7724 With PowerArchitect 5.0

The XRP7724 is unequaled in both standby current and power consumption performance with multiple Pulse Frequency Modulation (PFM) modes for improved light load efficiency. Additionally, the XRP7724 minimizes printed circuit board (PCB) space with the smallest solution footprint while significantly lowering external part count. The XRP7724 delivers a wide variety of features and capabilities that distinguishes programmable power from legacy analog solutions.

This announcement advances Exar's leadership position in programmable power system solutions, said James Lougheed, vice president of power management products. The part is really only limited by an architect's imagination, for example this solution could enable energy monitoring, remote field upgradability, or a dynamically optimized power system.

Product Details

The XRP7724 is Exar's next-generation programmable power management system. The system offers a single input, quad output, step down switching regulator controller with integrated gate drivers and dual LDO outputs. The product is programmable through an I²C based SMBus compliant serial interface. The system offers a wide input voltage range (4.75V to 25V), and output range (0.6V to 5.5V) with switching conversion frequencies programmable from 106kHz to 1.2MHz in digital Pulse Width Modulation (PWM) and PFM modes. The XRP7724 offers the industry's lowest power consumption performance in standby (450uA) and PFM mode (4mA). An additional five GPIOs for system control complete the solution which is delivered in a 7x7mm TQFN package.

PowerArchitect 5.0 is Exar's next-generation design tool to complement the XRP7724 product. This new release is a highly advanced tool that has been upgraded to support all the new hardware features of the XRP7724 including conditional sequencing, broader fault management, and more extensive GPIO configuration. The tool also includes improvements such as chip verify, auto-wizard inductor and capacitor value selection, multiple device communication and improved status and interrupt register management. The tool possesses an updated and more user friendly environment to aide designers in their increasingly complex power supply designs.
