2 / 6 page Exar’s PowerXR Digital Power Solutions Exar’s PowerXR ICs integrate the best of both worlds; the low cost and flexibility of digital power control as well as the robust power capabilities of high performance analog power switches. PowerXR products reduce development time from weeks to hours, enabling a significant time-to-market advantage for system design engineers. Additionally, Exar’s Digital Power Studio™ is an easy to use software environment, empowering engineers to create complex sequencing schemes and power systems, and modify voltage, current or other parameters in seconds. The PowerXR Product Family The PowerXR family is comprised of five Pluse-Width Modulated (PWM) step-down DC-DC controllers with a built-in LDO for standby power and GPIOs. The XRP7704, XRP7708, XRP7713, XRP7714, and XRP7740 devices provide a complete power management solution in one IC and are fully programmable via the included I²C serial interface. Independent Digital Pulse-Width Modulator (DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and over- voltage protection. Exar’s PowerXR Family Feature Advantage Benefit (re)configurability / Flexibility • Digitally (re)configurable SoC power supply solution • Reduces design effort by using simple GUI instead of changing hardware • Reduces risk by enabling customer to repair/ upgrade power supply when already at end-customer location • Use common platform across multiple customer designs Complete, Feature-Rich Power SoC Solution • Power SoC Solution replaces up to 13 discrete ICs in 6x6 mm package • Usable across a wide range of Vin, and broad cross-section of embedded processors, ASICs, or SOCs. • Replaces cumbersome discrete solutions, reduces footprint and cost of passive components Digital Power Studio™ • Rapid development, easy to use • Enables fast, simple design of complex power solution • Accelerates time to market from first meeting to production in as little as 2 weeks • Enable wide range of design engineers to leverage their level of expertise for optimal design Small SoC power supply solution with 4 power controllers, 1 LDO and all power management on a single chip. Power SoC Solution replaces up to 13 discrete ICs in 6x6 mm package. Excellent Efficiency Up to 93% efficiency on 4 combined voltage rails. Digitally (re)configurable SOC power supply solution Useable across a wide range of Vin, and broad cross-section of embedded processors, ASICs, or SOCs. Digital Power Studio™ enables fast, simple design of complex power solution. 50% 55% 60% 65% 70% 75% 80% 85% 90% 95% 100% 1 2 3 4 5 6 XRP7714 4-Channel Efficiency Vin = 5V Vout = 1 , 1.2, 1.8, 2.5V Iout = 5A max. 2 |
