FAN53600AUC33X is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists onsemi. Its product description is IC REG BUCK 3.3V 600MA 6WLCSP. Review the specifications below when checking this part for your BOM.
The FAN53600AUC33X is a synchronous buck switching regulator from onsemi. It provides a fixed 3.3V output with a maximum current of 600mA. The device operates at selectable switching frequencies of 3MHz or 6MHz. It accepts an input voltage range of 2.3V to 5.5V. The component is housed in a 6-pin WLCSP package. It features low quiescent current and supports shutdown mode for power efficiency.
Verify the specific suffix and package variant against official datasheets before ordering. Confirm availability status as distribution channels may vary. Ensure compatibility with existing PCB layout constraints regarding the WLCSP form factor. Check for any recent product change notices affecting electrical characteristics or pin assignments.
Select this component when a fixed 3.3V rail is required with moderate current demands up to 600mA. The choice between 3MHz and 6MHz frequencies depends on external inductor size preferences versus electromagnetic interference considerations. Evaluate thermal performance requirements based on the small package size and expected load conditions.
This part belongs to the FAN53600 series of synchronous buck regulators designed by onsemi. It is categorized under Power Management ICs (PMIC). The series targets applications needing compact solutions with high efficiency. It complements other regulators in the portfolio offering different voltage outputs or current capabilities.
Consult official substitution guides for compatible parts within the same family. Verify that alternative components match the 3.3V output, 600mA capability, and WLCSP-6 package dimensions. Ensure equivalent switching frequency options and control interface compatibility.
