SSD201

Overview

SSD201 is a wide input voltage, high efficiency active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. SSD201 provides up to total 3.5A output current at 5V output with floating ISET pin. Switching frequency can be set by external resistor. Maximum 100% duty cycle could be obtained. SSD201 internal integrated 45mΩ high side and 25mΩ low side power MOSFET.
