FAN48630BUC31JX Description

Short technical summary and product information.

The FAN48630BUC31JX from ON Semiconductor is a synchronous TinyBoost regulator, ideal for systems utilizing advanced Li-Ion battery chemistries. It provides a stable output voltage even when the battery voltage drops below the system's minimum requirement.

 

This IC features a 2.35V to 5.5V input voltage range and can deliver up to 1.5A of output current with a fixed output voltage option of 3.15V. Its high efficiency, up to 96%, helps maximize battery life. The regulator operates at a switching frequency of 2.5MHz and includes features like true bypass operation, soft-start, and short-circuit protection.

 

Designed for compact applications, the FAN48630BUC31JX is available in a 16-bump, 0.4mm pitch Wafer-Level Chip-Scale Package (WLCSP). It requires minimal external components, including a 0.47µH inductor and 0603 case size input/output capacitors, making it a space-saving solution. The operating temperature range is -40°C to 85°C.

 

With low operating quiescent current and a shutdown current of less than 3µA, this regulator is well-suited for portable electronics where battery longevity is critical. It also supports forced bypass mode to further reduce quiescent current when VIN exceeds the target VOUT.
