- Synchronous buck topology for high efficiency
- Fixed 1.233 V output configuration
- Compact 6-pin WLCSP footprint
Voltage Regulators - DC DC Switching Regulators Applications
- Portable consumer electronics
- Battery-powered devices
- Embedded systems power management
Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the manufacturer designation as Fairchild Semiconductor or onsemi, as corporate integration may affect labeling. Confirm the specific suffix UC123X corresponds to the fixed 1.233 V output variant. Ensure the package type matches the required 6-pin WLCSP specification for your PCB layout constraints.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 1.233 V rail is required at up to 1.2 A. The 6 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the input voltage range of 2.3 V to 5.5 V aligns with the system's power source characteristics.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the FAN5360x series of synchronous buck regulators. These ICs are designed for space-constrained applications requiring efficient power conversion from single-cell lithium-ion batteries or other low-voltage sources. The series emphasizes small form factors and high performance.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as variants with different fixed output voltages. Verify if newer generations from onsemi offer improved thermal performance or efficiency metrics while maintaining the 6 MHz frequency and WLCSP package.
