Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237A34D4R-G

The XC9237A34D4R-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage of 3.4V with a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and features a built-in P-channel MOS driver transistor with a resistance of 0.42Ω and an N-channel MOS switching transistor with a resistance of 0.52Ω. The device supports both PWM control and automatic PWM/PFM switching modes, allowing for efficient operation across varying load conditions. This regulator is optimized for low power consumption, with a standby current of less than 1.0OºA. It includes a high-speed soft-start feature, particularly beneficial for applications requiring quick turn-on times. The XC9237A34D4R-G is suitable for use with ceramic capacitors and is compliant with EU RoHS standards, making it an environmentally friendly option. It is available in multiple package types, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, providing flexibility for integration into various designs. Applications include mobile devices, digital cameras, and portable gaming consoles.
