onsemi Switching Regulator Surface Mount 6.5V DC, 800 mA Output Current FAN48685UC08X

onsemi FAN48685UC08X is a surface-mount switching regulator designed to provide a minimum voltage-regulated rail from single-cell Li-Ion batteries and advanced battery chemistries, suitable for battery-powered applications. It delivers a regulated output current of up to 800 mA at a maximum input voltage of 6.5 V DC, maintaining stable voltage even below the battery's minimum system voltage.

Featuring built-in power transistors and synchronous rectification, this low-power boost regulator achieves high efficiency of 93%, minimizing power loss and heat generation. Its package type is a 9-bump Wafer-Level Chip-Scale Package (WLCSP) with a 0.4 mm pitch, enabling compact circuit board designs.

The device operates reliably across a wide temperature range from -40°C to 85°C, making it suitable for diverse environmental conditions. Multiple output voltage levels - 3.6 V, 5.0 V, and 5.45 V - can be selected via MODE pins to meet different system requirements.

Key external components for optimal performance include a 0603 size inductor, a 0402 input capacitor, and two 0402 size output capacitors. The regulator minimizes ripple and noise to 30 mV, ensuring stable and clean power supply for sensitive electronics.

Typical applications include powering NFC modules, portable devices, and other embedded electronics where reliable and compact power regulation is critical. The FAN48685 series supports forced pass-through mode and supports efficient power management in constrained battery scenarios.

This product is RoHS-compliant and Pb-Free, adhering to industry environmental standards. It is ideal for electronics manufacturers, system integrators, and design engineers focusing on high-efficiency power regulation in compact formats.
