FAN53526UC00X Description

Short technical summary and product information.

The FAN53526UC00X from ON Semiconductor is a digitally programmable step-down (buck) switching voltage regulator. It is designed to deliver a continuous output current capability of 3.0 A from an input voltage range of 2.5 V to 5.5 V. The regulator operates at a fixed frequency of 2.4 MHz, which helps in reducing the size of external components.

 

This regulator features an I2C-compatible interface for digitally programming the output voltage, which can be set from 0.600 V to 1.39375 V in 6.25 mV steps. It also includes Pulse Frequency Modulation (PFM) for high efficiency in light-load conditions, with a typical quiescent current of 50 µA. For higher loads, it automatically switches to fixed-frequency control.

 

The FAN53526UC00X is available in a compact 15-bump, 1.310 mm x 2.015 mm, 0.4 mm ball pitch WLCSP package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C.

 

Key features include input under-voltage lockout (UVLO), thermal shutdown, and overload protection, making it suitable for applications such as processors, hard disk drives, LPDDR3/4, tablets, smartphones, and gaming devices.
