ADP2300/ADP2301 THEORY OF OPERATION The ADP2300/ADP2301 are nonsynchronous, step-down dc-to-dc regulators, each with an integrated high-side power MOSFET. A high switching frequency and ultrasmall, 6-lead TSOT package allow small step-down dc-to-dc regulator solutions. The ADP2300/ADP2301 can operate with an input ...
Page 15
SHORT-CIRCUIT PROTECTION The ADP2300/ADP2301 include frequency foldback to prevent output current runaway when there is a hard short on the output. The switching frequency is reduced when the voltage at the FB pin drops below a certain value, which allows ...

CATCH DIODE The catch diode conducts the inductor current during the off time of the internal MOSFET. The average current of the diode in normal operation is, therefore, dependent on the duty cycle of the regulator as well as the ...

ADP2300/ADP2301 THERMAL CONSIDERATIONS The ADP2300/ADP2301 store the value of the inductor current only during the on time of the internal MOSFET. Therefore, a small amount of power is dissipated inside the ADP2300/ADP2301 package, which reduces thermal constraints. However, when the ...
