The LP3971 Smart Power Board provides a complete: multi-rail solution for FPGAs: Microprocessors: or any other systems requiring multiple voltages: special power sequencing: and boot management. This solution utilizes the TI LP3971 Power Management Unit and an 8 bit microcontroller to manage the features of the PMU. There are more then billion combinations of initial voltage values for the output voltages: this solution can provide them all regardless the chip hard-coded startup values.An RS-232 port and Windows application are also provided to simplify evaluation of the solution using a PC; however: this is not required for a final system implementation.LP3971 Key specifications:Three Buck RegulatorsProgrammable V OUT from 0.8 to 3.3VUp to 95% efficiencyUp to 1.6A output current Six Accurate LDOsProgrammable VOUT of 1.0V-3.3V3% output voltage accuracy150/300/370mA output currents100mV (typ) dropout LDO 1 300 mA LDO 2 150mA LDO 3 150mA LDO 4 150mA LDO 5 370mA LDO RTC 30mA
