Overview
The FAN2356MPX is a synchronous buck regulator manufactured by Fairchild Semiconductor, now part of onsemi. It operates with an input voltage range of 4.5 V to 24 V and provides an adjustable output voltage from 0.6 V to 5.5 V. The device delivers a maximum continuous output current of 6 A. Key electrical parameters include a switching frequency range of 200 kHz to 1.5 MHz and a typical quiescent current of 24 µA. It utilizes a PQFN-34 package.
Feature Summary
- Integrated synchronous MOSFETs for high efficiency power conversion
- Adjustable output voltage via external resistor divider
- Wide input voltage range suitable for various bus voltages
- Programmable switching frequency to optimize performance
Applications
- Point-of-load (PoL) regulation in industrial systems
- Power distribution networks for embedded computing
- Telecommunications equipment power supplies
- High-current digital logic supply rails
Procurement Notes
Verify the manufacturer status as Fairchild Semiconductor was acquired by onsemi. Confirm the specific suffix 'MPX' matches the required PQFN-34 package variant. Check for end-of-life notifications or obsolescence warnings from the current manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a high-current, wide-input-range synchronous buck converter is required. Ensure the application demands an adjustable output voltage within the 0.6 V to 5.5 V range. Verify that the thermal requirements of the PQFN-34 package are met by the PCB layout design for adequate heat dissipation at full load.
Part Context
This part belongs to the FAN2356 family of high-efficiency point-of-load regulators. It is designed to replace older asynchronous solutions or lower-current regulators in applications requiring significant current delivery from higher voltage buses down to low-voltage digital cores.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official onsemi resources for direct pin-to-pin replacements or functional equivalents.
