Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '713' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the SOIC-Narrow-8 footprint matches the target PCB design guidelines. Ensure the commercial temperature grade meets the operational environmental constraints of the final system integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-cost solution is needed to generate a negative rail from a single positive source. The fixed 10 kHz switching frequency suits applications where electromagnetic interference is less critical than minimizing passive component count. Compare against through-hole variants if prototyping flexibility is prioritized over board space efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TC7660 series of charge pump converters, designed as direct replacements for legacy ICL7660 devices. The 'C' designation indicates the commercial temperature grade, while 'OA' specifies the SOIC-8 package type. The '713' suffix denotes the specific reel packaging format distributed by authorized channels.
