MP2363 – 3A, 27V, 365KHz STEP-DOWN CONVERTER The converter uses an internal N-Channel MOSFET switch to step-down the input voltage to the regulated output voltage. Since the MOSFET requires a gate voltage greater than the input voltage, a boost capacitor connected between SW and BS drives the gate ...

... A good rule of thumb is to set the is the load LOAD crossover frequency to approximately one-tenth of the switching frequency. Switching frequency for the MP2363 is 365KHz, so the desired crossover frequency is around 36.5KHz. Table 3 lists the typical values of compensation components for some standard output voltages with various output capacitors and inductors. ...
