Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the manufacturer status as Fairchild Semiconductor has been acquired by onsemi. Confirm the specific suffix 'C186DX' corresponds to the 1.8 V fixed output variant. Check for End-of-Life (EOL) notifications or obsolescence notices from the current manufacturer before finalizing procurement plans.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 1.8 V rail is required from a single-cell lithium battery source. The 600 mA limit suits low-power logic circuits. Ensure the PCB layout accommodates the small WLCSP footprint and thermal requirements associated with the 6.6 MHz switching frequency.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the FAN53601 family of 6 MHz synchronous buck regulators. The family includes variants with different output voltages and current ratings, such as the 1 A option found in the FAN53611. These components are designed for space-constrained portable electronics requiring high efficiency and minimal external component count.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
The FAN53601AUC10X is a documented equivalent offering a 1.0 V output instead of 1.8 V. Verify that the target circuit can accept the alternative voltage level. Other family members like the FAN53611 provide higher current capacity but may require different thermal management.
