XC9237A23DMR-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9237A23DMR-G is a synchronous step-down DC/DC converter from the Torex XC9237 series. It features a fixed output voltage of 2.3V and supports a maximum output current of 600mA. The device operates within an input voltage range of 2.0V to 6.0V and utilizes a 1.2MHz switching frequency. It employs current-mode control with selectable PWM or automatic PWM/PFM modes. The component is housed in a compact SOT-25-5 package and functions reliably across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DMR-G against official Torex documentation to confirm the SOT-25-5 package and 1.2MHz frequency variant. Ensure compatibility with required thermal dissipation standards for the target application environment. Cross-reference the fixed 2.3V output specification with system requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.3V output is required from an input range of 2V to 6V. It is suitable for designs prioritizing high efficiency across light to heavy load conditions through its selectable control mode. Consider the SOT-25-5 package constraints for PCB layout and thermal management during the design phase.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series, which are 600mA synchronous step-down converters. The series distinguishes itself by offering manual selection between PWM and PWM/PFM modes, unlike the XC9236 which switches automatically. The 'A' designation indicates a 2.0V minimum input voltage, while '23' specifies the fixed 2.3V output.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include other XC9237 variants with identical 2.3V output and SOT-25-5 packaging, such as XC9237A23CMR-G if pinout compatibility allows. Verify that substitute parts maintain the same 1.2MHz switching frequency and current rating.
