Programmable Power

Exar’s PowerXR products fuse digital power-supply control and monitoring technology with high-performance analog circuitry in a new generation of programmable power-management system solutions. PowerXR enables system architects to create products with advanced, integrated, switching power supplies that significantly reduce wasted energy and improve overall time to market compared to legacy analog power-supply regulators.

Power Conversion

Exar offers a complete family of DC to DC power conversion products for Point-of-Load (PoL) converters from linear LDOs and regulators to high-performance switching regulators and controllers covering applications with currents ranging from a few mA to over 30A. These products provide a complete power management solution for non isolated point of load converters operating from an intermediate bus in various distributed power architectures.

The XRP6124 is a non synchronous step-down (buck) controller for up to 5Amps point of loads. A wide 3V to 30V input voltage range allows for single supply operations from industry standard 3.3V, 5V, 12V and 24V power rails. With a proprietary Constant On-Time (COT) control scheme, the XRP6124 provides extremely fast line and load transient response while the operating frequency remains nearly constant at up to 1MHz operations.

Exar PowerBloxTM family of high voltage high current step-down regulators provides a high performance market proven solution for POLA replacement with capabilities of up to 12Amps and one the highest current density on the market. For 1.5Amps to 3Amps point-of-loads, the XRP7659, XRP7664 and XRP7665 provide a simple, performing and cost effective solution.

System Controls

Power delivery and control functions insure electronic systems and equipment 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.

The XRP2523 and XRP2524 are single and dual channels integrated high-side power distribution switch optimized for self or bus-powered applications and compliant with the USB 2.0 and USB 3.0 specifications. These devices provide an active high channel independent enable pin, integrated soft start and a blanked error flag indicating a fault condition.

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.

The XRP7613 is Exar’s dedicated step down switching regulators for driving high Power LEDs in architectural, ambient and MR16 lighting applications. Operating at up to 1MHz, which results in a minimum size solution, this PFM hysteretic device drives LEDs at up to 1.2A and operates at operates from a input voltage rail up to 36V.

The XRP6840 is the industry’s highest Intensity LED Flash driver and constant current dual-cell supercapacitor charger. With an I2C based programmable 4.3A Flash LED current, it provides all the function to manage and drive high brightness LEDs in portable equipment using the emerging supercapacitor technology.

The XRP7618 is an 8-channel constant-current LED driver capable of up to 100mA current per channel. Controlling strings of multiple LEDs with excellent accuracy, the XRP7618 can be paralleled to provide a performing backlighting solution for display and panels 10 inches and above.

an Exar Solution for Each Conversion Stage

Electronic systems include one or more power conversion stages. From a simple direct connection to a battery to more elaborate inter-connections, each power conversion stage is characterized by a few key parameters. The most important ones are the input voltage range (VIN) from which the conversion has to take place, the output voltage range (VOUT) that the conversion stage has to support and the amount of current or power the conversion stage has to be capable of providing (IOUT). Knowing those three key parameters identifies the type of solution that will be the most adequate to implement.

PowEr ConVErSion → SwitChinG rEGuLatorS → Step-up regulators

PowEr ConVErSion → SwitChinG ControLLErS → Step-down Controllers

Step-up regulators, also known as boost regulators, are used to step up an input voltage to the desired higher output level. They are typically used in portable equipment where the power supply is provided by a battery.

Step-down controllers, also known as buck controllers, are the basic element used to build high efficiency and high power point of loads. Driving one or two external FETs in respectively its synchronous or non synchronous versions, step down controllers allow the maximum flexibility and tailoring for high performance conversions.
