HT77S11 - High Efficiency Synchronous Step-Up DC/DC Converter

Download the HT77S11 datasheet PDF. This datasheet also covers the HT77S10 variant, as both devices belong to the same high efficiency synchronous step-up dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • Low start-up voltage: 0.7V (Typ. ).
  • High efficiency: HT77S10: 91% (Typ. ).
  • Low ripple and low noise.
  • Ultra low supply current: 20mA (Typ. ).
  • Low shutdown current: 1mA (Max. ).
  • Built-in voltage detector.
  • 8-pin MSOP/SOP packages at IOUT=200mA, VIN=2.4V, VOUT=3.3V.
  • High output voltage accuracy: ±4%.
  • Output voltage: 3.3V, 5.0V or Adjustable.
