Overview
The FAN23SV15MAMPX is a synchronous buck regulator manufactured by onsemi, designed for high-current applications. It operates with an input voltage range of 7 V to 24 V and delivers up to 15 A of output current. The device supports adjustable output voltages from 600 mV to 5.5 V and features a programmable switching frequency between 200 kHz and 1 MHz. Key electrical specifications include a maximum quiescent current of 24 uA and an operating supply current of 1.8 mA. It functions within a temperature range of -40°C to +125°C and utilizes a PQFN-34 surface-mount package.
Feature Summary
- Integrated synchronous rectification for improved efficiency in step-down conversion
- Programmable switching frequency allows optimization for size and performance
- Low quiescent current capability enhances system power management
Applications
- Point-of-load regulation for industrial equipment
- Power distribution systems in telecommunications infrastructure
- High-density power supplies for computing modules
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'MAMPX' matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS and REACH standards as documented in the official datasheet. Check for end-of-life status or obsolescence notices prior to final design approval.
Selection Notes
Select this regulator when a compact solution is needed for currents up to 15 A. The PQFN-34 package offers thermal efficiency for space-constrained designs. Verify that the required output voltage falls within the 600 mV to 5.5 V range. Ensure the input supply voltage remains within the 7 V to 24 V operational limits for stable regulation.
Part Context
This component belongs to the FAN23SV series of synchronous buck regulators from onsemi. The series focuses on delivering high efficiency and compact form factors for modern power management needs. The FAN23SV15MAMPX specifically targets applications requiring robust current handling in a small footprint.
Replacement Considerations
Consult the official onsemi product selection guide for direct pin-compatible alternatives within the FAN23SV family. Verify that any substitute part maintains identical electrical characteristics and package dimensions.
