MP2354 – 2A, 23V, 380KHz STEP-DOWN CONVERTER

External Bootstrap Diode

It is recommended that an external bootstrap

diode be added when the system has a 5V

fixed input or the power supply generates a 5V

output. This helps improve the efficiency of the

regulator. The bootstrap diode can be a low

cost one such as IN4148 or BAT54.

This diode is also recommended for high duty

cycle operation (when VOUT >65%) and high

VIN

output voltage (VOUT>12V) applications.
