Product Number: XRP7704EVB Evaluation Board for XRP-7704 -- Programmable Power System ICs Reduce Development Time, Cost and are Easily Reconfigured for Real-time Design Changes Exar has released the XRP7704, a 5Amp/channel regulator. These power ICs integrate the best of both worlds - the low cost and flexibility of digital power management and control, and the robust power capabilities of analog switching XR power supplies. Power products will reduce development time from weeks to hours enabling a significant time-to-market advantage. This PowerXR device permits real- time power system adjustments during design, in response to changing requirements or even after field-deployment. The XRP7704 is the first 5-channel power-system ICs to combine high performance analog technology with advanced, high-speed, proprietary digital control circuitry. These ICs deliver on the promise of Digital Power by providing engineers with a cost effective configurable power solution. Key Product Features This XRP704 device offers a wide input voltage range (6.5V to 20V), and output range (0.9V to 5.0V), with a built-in Low-Drop Out (LDO) for standby power, power sequencing capability, and integrated gate drivers. The 5-output, XRP7704 digital power system controller ICs contain four digital pulse width modulator (DPWM) controlled power supplies with an effective 12-bit resolution. This device also contains an integrated LDO regulator that provides a fifth voltage supply, which can also be employed as a standby-voltage source. The chip is fully configurable via an IC interface for monitoring, control and management of DC/DC point-of-load power conversion. The device contains integrated gate drivers for the high-current outputs and up to 6 General Purpose Input/Output (GPIO) pins. The XRP7704 uses a digital PID (proportional, integral, differential) control algorithm which performs full-digital loop control at switching frequencies to 1.5 MHz. The controller supports IC interface commands for control, configuration, and management of the power supply.
