These architectures include a state-of-the-art family of PID based programmable power solutions providing dynamic control and real time telemetry. These programmable power solutions include fully integrated modules to configurable universal PMICs. With over 40 years of analog and mixed-signal expertise, Exar’s power solutions are trusted everyday to provide an unprecedented combination of high efficiency, high performance, board space optimization and improved system reliability while reducing costs and time to market. Programmable Power Exar’s Programmable Power Modules and Universal PMICs offer advanced dynamic control and telemetry along with remote re-configurability. PowerArchitect™ design and configuration software speeds development and significantly reduces overall time to market compared to legacy analog power solutions. An I²C interface and multiple GPIO pins ensure easy system integration. Configurable warning and fault levels, fault behavior, and power up and down sequencing ensure any load can be properly powered and protected. The power system design can be completed with confidence long before the final revision of the SOC or ASIC is available. Modules offer the ultimate in power density and simplicity with an industry leading dual 6Amp output in a 12x12x2.75mm solution. The XRP7725 Intel Node Manager Compatible Quad Output controller brings a high level of system telemetry beyond what is normally available through standard I2C interfaces. All products in this class feature purpose built state machines with patented programmable PID control loops resulting in lower power consumption and faster transient response than any other “digital” solutions on the market today. Power Conversion Exar offers a complete family of DC to DC power conversion products from best in class vultra-low voltage ultra-LDOs such as the XRP6275 to standard linear LDOs and regulators, and high-performance switching regulators and controllers covering applications with currents ranging from a few mA to over 30A. The new XR75100 raises the maximum input voltage capability of Exar’s controllers to 40V, ideal for a wide range of industrial application. These products provide a complete power management solution for non-isolated conversions operating from an intermediate bus in various distributed power architectures. Exar’s PowerBlox™ family of high current step-down regulators provides a high performance market proven solution for with capabilities of up to 15Amps. The new XR761108, XR76112, and XR76115 provide even faster transient response, 0.5% output voltage accuracy, and a full set of features allowing the designer to meet a wide range of requirements. Also available is a cost effective broad product offering of switching regulators from 800mA to 6A outputs and inputs from 2.5V to 28V. System Controls Power delivery and control functions insure electronic systems and equipments operate at the anticipated performance level and within the required safety margins. While stable voltage references guarantee accurate power generation, system supervisors monitor one or several voltage rails for abnormal operations. Power switches are key elements of power distribution providing on/off functionalities along insuring over current protection for the equipment and peripheral systems. LED Lighting Efficiency, performance, size and reliability are rapidly imposing LEDs as the lighting solution of choice in space constrained portable electronic equipment as well as in architectural and accent lighting fixtures. Exar’s LED lighting products offers compact and efficient solutions for line and battery-operated devices and are capable of driving multiple LEDs in various series or parallel topologies. 4 POWER MANAGEMENT PORTFOLIO Programmable Power Programmable Power Management Systems Triple PMIC Quad PMICs XRP7713 Modules XRP7704 XRP7708 XRP7714 XRP9710 XRP7720 XRP7724 XRP7725 XRP9711 XRP7740 Power Conversion Switching Controllers Switching Regulators Linear Step-down Step-down (Dual) Step-down PowerBlox™ Step-up Step-down SP6650 XRP6668 SP7650 SP6660 SP6120 LP2950 SPX1583 SPX2941 SP6651 SP7651 SP6661 SP6121 LP2951 SPX1117 SPX2945 SP6652 SP7652 SP6641 SP6123 SP1086 SPX1521 SPX29501 SP6654 SP7656 SP6644 SP6126 SP6200 SPX1582 SPX29502 SP6656 SP7662 SP6648 SP6128 SP6201 SPX1583 SPX2951 SP6669 SP7663 SP6132 SP6203 SPX1587 SPX2954 XRP6657 XRP7657 SP6133 SP6205 SPX2815 SPX3819 XRP6658 XRP7662 SP6134 SP6213 SPX29150 SPX3940 SP34063 XRP7664 SP6136 SP6214 SPX29151 SPX5205 XRP6670 XRP7665 SP6137 SP6260 SPX29152 XRP29302 XRP7659 XRP6124 SPX1117 SPX29300 XRP6272 XRP7674 XRP6141 SPX1521 SPX29301 XRP6274 XRP7675 XRP6142 SPX1582 SPX29302 XRP6275 XR76108 XR75100 SPX1583 SPX2940 LDOs DDR XRP2997 XR76112 XR76115 System Controls Voltage References Power Switches - USB 2.0/3.0 Supervisors Single Dual SPX1431 SPX2431 SP690 SP691 SP705 SP2525A SP2526A SPX385 SPX431 SP706 SP707 SP708 XRP2525 XRP2526 SPX432 XRP431 SP791 SP809 SP810 XRP2527 XRP2528 XRP2523 XRP2524 SP813 SP619 LED Lighting Switching Regulators Linear Drivers Step-down Step-up/down Step-up XRP7613 SP6685 SP6682 XRP7618 SP6686 SP6683 XRP7620 SP7685 SP6887 SP7686 SP6699 XRP6840 SP7648 5 PROGRAMMABLE POWER → Programmable Power Management Systems Exar’s Programmable Power Modules and Universal PMICs offer advanced dynamic control and telemetry along with remote reconfigurability.
