Additional Details

The XC9210B093KR operates with a switching frequency of 1.2MHz, allowing for the use of small external components. It incorporates a soft-start function to suppress inrush current during startup. The integrated N-channel MOSFET contributes to the high efficiency of the converter. The device is available in a SOT-25 package, which is a small and thin package suitable for space-constrained applications. The device also integrates an under voltage lockout (UVLO) function to protect the device from operating with low input voltages. The exact output current capability is dependent on the specific input and output voltage conditions, and should be verified based on the datasheet.
