Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DB' corresponds to the MSOP-8 package and active status. Confirm RoHS compliance details as indicated in official documentation. Check for any recent Product Change Notifications (PCN) that may affect pinout or material composition. Ensure the ordering part number matches the required output voltage configuration options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for boosting single-cell lithium-ion or alkaline battery voltage is required. The MSOP-8 package minimizes PCB space compared to larger packages. Consider the 1MHz switching frequency for smaller passive components. Verify that the 750mA input current limit meets the load requirements of the target ASIC or microprocessor.

Voltage Regulators - DC DC Switching Regulators Part Context

The L6920DB belongs to the L6920 series of synchronous rectifier step-up converters by STMicroelectronics. This series is categorized under PMIC - Power Management ICs. The 'DB' suffix typically denotes the MSOP-8 package variant within this family, distinguishing it from other package options like DCTR.
