LtdThe XCL207A183CR-G from Torex Semiconductor Ltd is a step-down microDCDC converter with integrated 600mA inductor and PWM switching voltage regulators. It is designed for use in portable and battery-powered devices, providing high efficiency over a wide input voltage range of 2.3V to 6V, and a fixed 3.3V output at up to 600mA. It also features an active current limit for improved load response and accuracy, an adjustable soft start, enable input, and an output voltage detection voltage detection pin. The XCL207A183CR-G offer low quiescent current, and an integrated protection circuit for over-voltage, over-current, and short-circuit protection.
