HT77S11, HT77S10, High Efficiency Synchronous Step-Up DC/DC Converter
The HT77S11 and HT77S10 are high efficiency PFM synchronous step-up DC-DC converters.
The two devices although functionally similar are different in their output drive current capabilities.
Synchronous rectification operation is used to increase device efficiency and to reduce the external component
