On/Off input may be used for the Analog Dimming Thermal protection Cycle-by-cycle current limit ILOAD max =2A VOUT from 0.2V to 55V SOP-8 Package Available Immense Advance Tech. 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 ISTBY~50µA (typ.). The ON/OFF pin may be used
