  • Description

    The XCM403AA02SR is a multi-module IC that combines a step-down DC/DC controller IC with a P-channel power MOSFET. It is designed to provide a high efficiency and stable power supply with an output current of up to 3A. To achieve this, low ESR electrolytic capacitors such as OS-CON aluminum solid capacitors or tantalum Neo capacitors can be used as the output capacitor. If a ceramic capacitor is used, RSENSE needs to be added. The XCM403AA02SR has a reference voltage of 0.9V (±1.5%) and allows for the output voltage to be set freely using externally connected resistors. It operates at a switching frequency of either 500kHz or 1.0MHz, allowing for the use of small external components. The XCM403AA02SR also offers two types of soft-start time settings, with one being internally set to 4ms and the other being externally customizable. Furthermore, it includes an Under Voltage Lock Out (UVLO) function that turns off the internal P-channel driver transistor when the input voltage drops to 2.3V (TYP.) or lower.
