FAN48632UC35X Description

Short technical summary and product information.

The FAN48632UC35X from ON Semiconductor is a pulsed-load synchronous regulator with bypass mode, operating at 2.5 MHz and capable of handling 2.0 A pulsed load current. It is designed to provide a stable output voltage from single-cell Li-Ion batteries, even when the battery voltage is below the system's minimum requirement.

 

This regulator supports an input voltage range of 2.35 V to 5.5 V and offers fixed output voltages of 3.5 V or 3.7 V. It boasts high efficiency up to 96% and features true bypass operation when the input voltage exceeds the target output voltage. The device includes internal synchronous rectification, soft-start with true load disconnect, and short-circuit protection.

 

Packaged in a compact 16-bump, 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP), the FAN48632UC35X is suitable for space-constrained designs. Its applications include boosting low-voltage Li-ion batteries, brownout prevention, and supplying GSM RF PA in devices like cell phones and tablets.
