FAN48685UC08X Description

Short technical summary and product information.

The FAN48685UC08X is a fixed-output synchronous TinyBoost/C0041 regulator designed by On Semiconductor. It is engineered to deliver a minimum voltage-regulated rail from standard single-cell Li-Ion batteries and advanced battery chemistries, maintaining output voltage regulation for load currents up to 800 mA, even when the battery voltage is below the system minimum.

 

This device features an input voltage range of 2.5 V to 5.5 V and offers three programmable output voltages: 3.6 V, 5.0 V, and 5.45 V, selectable via MODE pins. The regulator operates at a switching frequency of 2.5 MHz and includes built-in power transistors and synchronous rectification for improved efficiency and reduced component count.

 

The FAN48685UC08X is supplied in a compact 9-bump, 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP), making it suitable for space-constrained battery-powered applications. It requires only four external components: a 0603 inductor, and 0402 case size input and two output capacitors. This regulator is also a Pb-Free device.

 

Key applications include NFC module power. The device operates within a temperature range of -40°C to 85°C.
