Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the 'L' designation aligns with the intended output voltage setting or package variant if multiple options exist within the series. Ensure the ordering code matches the required switching frequency selection pin configuration. Cross-reference the datasheet revision date to confirm thermal and electrical specifications remain unchanged.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage range of 1.8V to 6.0V is required with up to 600mA output. Choose the adjustable version over fixed variants if precise voltage tailoring is needed. Consider the automatic PWM/PFM mode for applications prioritizing battery life at light loads. Verify that the selected switching frequency (1.2MHz or 3.0MHz) suits the size constraints of the external inductor and capacitor components.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9236 series, which are synchronous-rectification type DC/DC converters. The series includes variants with different fixed outputs and reference voltages. The XC9236 series is distinguished by its automatic switching control mode, unlike the XC9235 (PWM only) and XC9237 (manual switch) series. It shares the same internal transistor architecture and package options as other members of the family.
