The KP521403LGA with TSOT23-5 DC-DC Converters ROHS manufactured by KIWI is a low-power, highly efficient, step-down DC/DC converter designed for mobile and other battery-powered applications. It operates with an input voltage range of 2.4 V to 5.5 V and provides a selectable output voltage range from 1.8V to 5 V, both adjustable with external resistors. The maximum output current is 3 A. It also features a low quiescent current (typical 10µA) to reduce power dissipation and system heat. The device is ideally suited for LED drivers, battery chargers, and other portable applications, thanks to its very low no-load supply current and multi-function shutdown feature. The device is AEC-Q100 Grade-1 certified and is RoHS compliant.
