Overview
The FAN53880UC002X is a Power Management IC (PMIC) designed for mobile power applications, featuring low quiescent current operation. It integrates one buck converter, one boost converter, and four low-noise LDOs. The device supports an input voltage range up to 5.5 V. Output capabilities include a buck output adjustable from 600 mV to 5.7 V. The component is RoHS compliant and packaged in a compact form factor suitable for space-constrained designs.
Feature Summary
- Integrates multiple regulation topologies including buck, boost, and LDO regulators within a single package
- Optimized for low quiescent current consumption in mobile power applications
- Provides four low-noise LDO outputs for sensitive analog circuitry
Applications
- Mobile power systems
- Portable electronic devices requiring integrated power management
- Applications needing combined step-down, step-up, and linear regulation
Procurement Notes
Verify the specific suffix UC002X against official onsemi documentation to confirm pinout, thermal characteristics, and electrical tolerances. Ensure compatibility with target PCB layout requirements. Confirm RoHS compliance status through current datasheets. Check for any recent Product Change Notifications (PCNs) affecting material composition or manufacturing location before finalizing procurement orders.
Selection Notes
Select this PMIC when a single solution is required to manage buck, boost, and multiple LDO rails simultaneously. Consider its low quiescent current specification for battery-operated mobile applications. Evaluate the integration level against discrete solutions to assess board space savings. Verify that the input voltage range and output current capabilities meet the system's peak and average load requirements.
