XC9276DB900R-G

XC9276DB900R-G is a XC9276 series 150mA step-down synchronous rectification DC/DC converter which has an output voltage switchover function with an ultra-low power consumption circuit and a PFM control. The efficiency performance at a light load current is dramatically improved by implementing ultra-low power consumption circuits which has 200nA consumption current, and PFM control method. Additionally, two-preset output voltage switchover function is available with using VSET pin. This function can select an appropriate output voltage based on the MCU behaviour mode and contribute a power consumption reduction for a total system. Due to this function, it is suitable for equipment which needs a high efficiency performance at a light load current, and a long-time battery life. Application includes smart meter, low power RF, sensor module, wearable devices, energy harvest devices, back-up power supply circuit, smart card, devices with 1 lithium cell.
