The FAN48615UC11X is a low-power PWM boost regulator designed for battery-powered applications, specifically optimized for use with single-cell Li-Ion batteries and advanced battery chemistries. It provides a fixed output voltage of 5.4 V with a maximum load capability of 1000 mA, ensuring voltage regulation even when the input voltage drops below the minimum system battery voltage. This device features an input voltage range of 2.7 V to 5.5 V and achieves efficiency levels of up to 97%. It incorporates internal synchronous rectification and offers true load disconnect functionality, along with short-circuit protection. The regulator is packaged in a compact 9-bump, 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP), measuring 1.215 x 1.215 mm. The FAN48615UC11X is suitable for various applications, including Class-D audio amplifiers, portable devices, and RF/NFC applications. It requires only three external components: a 0.47 µH inductor and input/output capacitors, making it a straightforward solution for engineers looking to implement a reliable boost regulator in their designs.
