Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SVP' against official datasheets to confirm the intended application variant, as other suffixes like 'OOP' or 'ZXP' exist within the same family for different voltage requirements. Ensure compatibility with the target PCB footprint for the 15-WLCSP package. Confirm that the design supports the required 2.4 MHz switching frequency and I2C communication protocols before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for the Genio 1200 ecosystem requiring a dedicated 3A rail for LPDDR4X memory. Choose this part over alternatives if the application strictly requires the 0.27V-1.4V output range and 2.4 MHz frequency. Consider thermal dissipation capabilities inherent to the WLCSP form factor. Validate that the input voltage range of 2.5V to 5.5V aligns with the system's primary power source.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the MediaTek Genio series Power Management Integrated Circuits (PMIC).
