XA2361
PFM Step-Up DC-DC Converter
General Description
The XA2361 Series are PFM step-up DC-DC converters with very low ripple noise due to the high operation frequency. The maximum operation frequency is 260KHz.
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.
