DC to DC converters for 3 to 85V are important in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily.
DC to DC converter 3 to 85 V Circuit
Circuit above is electronic devices often contain several sub-circuits, each with its own voltage level requirement different than that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage, and possibly even negative voltage). Additionally, the battery voltage declines as its stored power is drained. Switched DC to DC converters offer a method to increase voltage from a partially lowered battery voltage thereby saving space instead of using multiple batteries to accomplish the same thing.
