... The Si9166 is capable of switching MHz to minimize the output inductor and capacitor size in order to decrease the overall converter size. The Si9166 is available in both standard and lead (Pb)-free TSSOP-16 pin packages and specified to operate over the industrial temperature range of −25_C to 85_C. ...

... The logic high enables the controller and starts up as described in Start-Up section above. MODE Selection The Si9166 can be programmed to operate as Buck or Boost converter. If the MODE pin is connected to AGND, it operates in buck mode. If the MODE pin is connected boost mode. The DH gate drive output is designed to drive ...

... Si9166 Vishay Siliconix Oscillator The oscillator is designed to operate up to 2-MHz minimal. The 2-MHz operating frequency allows the converter to minimize the inductor and capacitor size, improving the power density of the converter. Even with 2-MHz switching frequency, quiescent current is only 500 mA with unique power saving circuit design ...
