20150229160 | POWER FAILURE PREVENTION SYSTEM AND CIRCUITS - A DC-DC converter system that can switch between BOOST and BUCK operation is used in a power failure prevention system. The DC-DC converter operates in BOOST mode at startup. It charges a storage capacitor via an inductor having its peak current controlled, together with a soft start ramp to limit the power supply in-rush current. During power failure, if the storage capacitor is charged above a pre-determined threshold and the input power supply discharges below a programmable threshold, the DC-DC converter switches from BOOST to BUCK mode, detectable through an internal power detection circuit; its output may also control an external/internal power switch that isolate the input main supply from the power bus. The BUCK mode converter will then dump the charges from the storage capacitor back to the power bus. The BOOST to BUCK mode seamless switchover is achieved through an analog/digital multiplexer that simplify the circuit implementation. | 08-13-2015 |
