DESCRIPTION
AT7450 is the monolithic IC designed for a step-down DC/DC converter capable of driving 2A load without an additional transistor.
The input
voltage range is up to 60V.
Its feedback
voltage, VFB, is 200mV.
The AT7450 operates at a switching frequency of 52kHz.
The external shutdown function
is controlled by a logic level on the ON/OFF pin and then the circuit comes into the standby mode with
