Voltage Regulators - DC DC Switching Regulators datasheet and documents for FAN53741UC108X

FAN53741UC108X

Voltage Regulators - DC DC Switching Regulators Overview

The FAN53741UC108X is a synchronous step-down DC-DC converter manufactured by onsemi, formerly Fairchild Semiconductor. It operates with an input voltage range of 2.7V to 5.5V and provides a single adjustable output from 0.6V to 3.3V at up to 1A load current. The device integrates a 2.2MHz switching frequency for compact passive design. It utilizes a 10-bump WLCSP package (UC) with a specific 1.08V fixed output configuration suffix (108).

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous rectification architecture for high efficiency across the load range.
Integrated power switches eliminate external component requirements.
Fixed output voltage option simplifies board layout and design time.

Voltage Regulators - DC DC Switching Regulators Applications

Portable consumer electronics requiring efficient power management.
Battery-powered devices needing extended runtime.
Embedded systems with strict space constraints.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as onsemi due to corporate acquisition history. Confirm the exact suffix '108' corresponds to the required fixed output voltage. Check RoHS compliance status in the latest datasheet. Ensure the WLCSP package handling requirements are met during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed output voltage is preferred over adjustable variants to reduce external resistor networks. Consider the 1A current limit for moderate load applications. Evaluate the WLCSP footprint against available PCB real estate. Compare thermal performance requirements against the small package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN5374x series of synchronous buck regulators. It shares architectural similarities with other members like the FAN53745 but differs in output configuration and specific pinout details. The series targets low-power portable applications requiring high efficiency in minimal space.
