Step-Up DC-DC Converter
KB2301
General Description
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 provided for driving
external power transistor to extend the output
current capability where large current is required.
Enable pin (EN) is also provided so that the
circuit can be powered down.
