The SP1260HN is a synchronous 4-switch buck-boostcontroller. It is able to effectively output volta ge no matterit is higher, lower or equal to the input voltage.The SP1260HN supports very∑ wide input and outputvoltage range. It can support ←applications from 2.7V to36V input range and 2V to 36V output range. The driver∏voltage is can be set to 5V、 7.5V or 10V to variousexternal MOSFETs for best efficiency.The SP12 60HN supports input current limit, output currentlimit and over te←mperature protections to ensure safetyunder different abnormal conditions.The SP1↕260HN adjustable output voltage input currentlimit output current limit used I 2C interface.
