Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237A23CMR-G

The XC9237A23CMR-G is a synchronous step-down DC/DC converter from Quarktwin Technology Ltd., 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 to a fixed value of 2.3V, making it suitable for applications requiring a specific voltage level. This regulator 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 device supports two oscillation frequency options of 1.2MHz and 3.0MHz, which can be selected based on application needs. It also includes a manual PWM/PFM switching control mode, enabling flexibility in managing power efficiency across varying load conditions. The XC9237A23CMR-G incorporates several protective features, including a built-in under-voltage lockout (UVLO) function and a current limiter circuit. In standby mode, it consumes less than 1.0OºA, contributing to overall energy efficiency. The product is available in multiple package options, including SOT-25, USP-6C, and USP-6EL, making it adaptable for various design requirements. This regulator is suitable for applications in mobile devices, Bluetooth technology, and portable gaming consoles.
