Overview
The FAN48619UC50X is a fixed-output synchronous TinyBoost regulator manufactured by onsemi. It operates within an input voltage range of 2.7 V to 4.5 V and provides a fixed 5 V output with a maximum output current of 1 A. The device features a low static current of 48 uA and operates at a switching frequency of 2.3 MHz. It is housed in a BGA-9 package and supports surface mount installation. The component functions across a temperature range from -40 C to +85 C.
Feature Summary
- Synchronous rectification for improved efficiency
- TinyBoost topology for compact design
- Low quiescent current operation
Applications
- Portable electronic devices
- Battery-powered systems
- Mobile communication equipment
Procurement Notes
Verify the specific revision level and packaging configuration against the official datasheet before procurement. Confirm that the BGA-9 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives as specified in the manufacturer documentation. Cross-reference the part number suffix to guarantee the correct output voltage and thermal characteristics.
Selection Notes
Select this component when a fixed 5 V output is required from a single-cell lithium-ion battery source. The 1 A current capability suits moderate load applications. Consider the 2.3 MHz switching frequency for balancing component size and EMI performance. Verify that the 48 uA static current meets the standby power requirements of the system design.
Part Context
This part belongs to the FAN48619 series of TinyBoost regulators. It is designed for space-constrained portable applications requiring efficient step-up conversion. The synchronous architecture distinguishes it from non-synchronous alternatives in the same family, offering higher efficiency at light loads.
Replacement Considerations
Check for direct pin-compatible substitutes within the FAN48619 series. Verify if other onsemi TinyBoost regulators offer compatible input ranges and output currents. Ensure any replacement maintains the BGA-9 package form factor.
