Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237A2HD0R-G

The XC9237A2HD0R-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage with high efficiency. It operates within an input voltage range of 2.0V to 6.0V and can deliver an output current of up to 600mA. The output voltage can be set externally from 0.9V to 6.0V using two external resistors, or it can be fixed at various levels from 0.8V to 4.0V depending on the specific type. The device features a built-in 0.42Oc P-channel MOS driver and a 0.52Oc N-channel MOS switching transistor, allowing for the use of low ESR ceramic capacitors. The XC9237 series allows for manual switching between PWM control mode and automatic PWM/PFM switching control, which enhances performance across varying load conditions. It includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function that disables the output when the input voltage falls below 1.4V. The device is available in multiple package options, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, making it suitable for various applications including mobile devices, digital cameras, and portable gaming consoles.
