KB2301 Step-Up DC-DC Converter

The kB2301 Series are PFM step-up DC-DC converters with very low ripple noise due to the high operation frequency. The maximum operation frequency is 400KHz. Only three components are required to realize the conversion from the battery voltage to a selected output voltage. A driver pin (EXT) is prov.
