Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237A2FD0R-G

The XC9237A2FD0R-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in P-channel MOS driver transistor with a resistance of 0.42Oc and an N-channel MOS switching transistor with a resistance of 0.52Oc. The operating voltage range is from 2.0V to 6.0V, with an output current capability of up to 600mA. The output voltage can be set externally from 0.9V to 6.0V or can be fixed within a range of 0.8V to 4.0V, depending on the configuration. This regulator supports oscillation frequencies of either 1.2MHz or 3.0MHz, allowing for flexibility in application requirements. The XC9237 series specifically allows manual switching between PWM control and automatic PWM/PFM switching control modes, which enhances performance across varying load conditions. The device includes features such as a built-in soft start, current limiting, and an under-voltage lockout (UVLO) function to ensure safe operation. Additionally, it has a low standby current consumption of 1.0OºA or less, making it suitable for battery-powered devices. The XC9237A2FD0R-G is available in multiple package options, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, catering to different design needs. Its applications include mobile devices, digital cameras, and portable gaming consoles, making it a versatile choice for engineers looking for reliable voltage regulation solutions.
