FAN53526UC96X-FS

Product Overview

The Fairchild Semiconductor FAN53526UC96X-FS is an Active TinyBuck step-down switching regulator for positive output applications. It provides a programmable single output from 0.6V to 1.39375V at up to 3A, with a 2.4MHz switching frequency and synchronous rectification. The device operates from a 2.5V to 5.5V input supply and is supplied in a 15-UFBGA, WLCSP surface-mount package.

Key Features

• Step-down buck topology with one positive programmable output
• Input voltage range: 2.5V to 5.5V
• Output voltage range: 0.6V to 1.39375V at 3A
• 2.4MHz switching frequency with synchronous rectifier
• 15-WLCSP (2.02x1.31) surface-mount package
• Operating temperature range: -40°C to 85°C (TA)

Applications

• Point-of-load regulation for low-voltage loads within the specified output range
• Power conversion for boards using 2.5V to 5.5V input rails
• Surface-mount designs needing a small 15-WLCSP footprint and programmable output

Design & Procurement Notes

For design and procurement, confirm that the input rail remains within 2.5V to 5.5V and that the required load does not exceed 3A at the selected programmable output voltage. The 2.4MHz switching frequency and synchronous rectifier influence external component selection and layout choices. The 15-UFBGA, WLCSP package requires surface-mount assembly and footprint review, while the -40°C to 85°C operating temperature range should be checked against the final environment. The supplied lifecycle status is Active.
