Overview
The FAN48695UC190X is a synchronous boost DC/DC converter manufactured by onsemi, designed for efficient power management in compact applications. It operates within an input voltage range of 2.5 V to 5.5 V and provides a fixed output voltage of 5 V with a maximum output current capability of 1 A. The device integrates PFM/PWM control modes and functions at a switching frequency of 2.5 MHz. Key electrical specifications include a low quiescent current of 27 uA and an operating temperature range from -40°C to +85°C. It is housed in a WLCSP-9 package.
Feature Summary
- Integrates PFM/PWM control modes for optimized efficiency across varying load conditions
- Features synchronous rectification architecture to enhance conversion performance
- Includes shutdown functionality for effective power management
Applications
- Portable electronic devices requiring compact power solutions
- Battery-powered systems needing efficient voltage boosting
- Embedded applications utilizing single-cell lithium-ion or similar power sources
Procurement Notes
Verify the specific suffix UC190X against official datasheets to confirm the fixed 5V output configuration and WLCSP-9 packaging details. Ensure compatibility with required thermal and electrical constraints for the target application environment before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 5V output is required from a 2.5V to 5.5V input source. Consider its 1A current capacity and 2.5MHz switching frequency for designs prioritizing small passive component sizes. Evaluate the WLCSP-9 package suitability for space-constrained PCB layouts.
Part Context
This part belongs to the FAN48695 series of synchronous boost regulators from onsemi. It shares architectural similarities with other TinyBoost family members but is distinguished by its specific output voltage setting and package type. The series targets portable electronics requiring high efficiency in minimal footprints.
Replacement Considerations
Consult official substitution guides for compatible parts within the FAN4869x series or equivalent onsemi boost regulators. Verify pinout and electrical parameter alignment before considering alternatives.
