FAN2011EMPX

Overview

The FAN2011EMPX is a synchronous step-down DC-DC switching regulator from onsemi, designed for high-efficiency power conversion. It operates with an input voltage range of 3V to 24V and delivers a maximum output current of 1.5A. The device features an adjustable output voltage ranging from 800mV to 19.2V. It integrates internal synchronous rectification to minimize external component count and improve efficiency. The regulator supports a switching frequency of up to 1.6MHz, allowing for the use of small inductors and capacitors. It is housed in a compact 6-WDFN package with an exposed pad for thermal dissipation.

Procurement Notes

Verify the specific suffix 'EMPX' against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration. Check for end-of-life status or obsolescence notices as availability may be limited. Ensure the selected package variant matches the PCB footprint requirements. Confirm RoHS compliance documentation is available for regulatory adherence. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact, high-efficiency buck converter is needed for low-current applications. Consider the 1.6MHz switching frequency for minimizing passive component size. Evaluate thermal performance given the 6-WDFN package constraints. Compare against alternative regulators if higher output current or different input voltage ranges are required. Verify that the adjustable output range meets the specific load requirements of the target circuit.

Part Context

The FAN2011EMPX belongs to the FAN2011 series of synchronous buck converters from onsemi. This series is designed for applications requiring high efficiency and small solution size. The EMPX designation typically indicates a specific tape-and-reel packaging option. The device is part of onsemi's portfolio of power management integrated circuits aimed at improving system reliability and reducing overall power consumption in portable and industrial electronics.

Replacement Considerations

Check for direct pin-to-pin replacements within the FAN2011 family or newer generations from onsemi. Verify compatibility with existing PCB layouts and thermal designs. Ensure substitute parts meet the same electrical specifications for input voltage, output current, and switching frequency. Review any changes in control loop stability or transient response characteristics.
