FAN5365UC00X

IC REG BUCK PROG 0.75V 9WLCSP

Manufacturer: Fairchild Semiconductor

Categories: DC DC Switching Regulators

Quality Control: Learn More

The Fairchild Semiconductor FAN5365UC00X is a high-efficiency, synchronous buck switching regulator designed for portable applications requiring compact size and superior power management. This component offers a programmable output voltage ranging from 0.75V to 1.44V, supported by an 800mA output current capability. Operating at a fixed switching frequency of 6MHz, the FAN5365UC00X minimizes external component size and reduces noise. Its advanced buck topology with integrated synchronous rectification ensures high efficiency across a wide range of load conditions. The device features a minimal input voltage range of 2.3V to a maximum of 5.5V. Packaged in a compact 9-WLCSP (1.22x1.22), it is ideal for space-constrained designs in consumer electronics, mobile devices, and other portable power solutions. Operating temperature range is -40°C to 85°C.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
