HT77S10 Datasheet (Holtek Semiconductor) - High Efficiency Synchronous Step-Up DC/DC Converter

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
