FAN53600AUC28X

Voltage Regulators - DC DC Switching Regulators Overview

The FAN53600AUC28X is a synchronous buck regulator from onsemi, operating at a fixed switching frequency of 3 MHz. It delivers an output current of up to 1 A with a fixed output voltage of 2.8 V. The device accepts an input voltage range between 2.3 V and 5.5 V. It is housed in a compact 6-UFBGA (WLCSP) package and supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification for high efficiency across load ranges
• Utilizes a small footprint WLCSP package suitable for space-constrained designs
• Operates at a fixed 3 MHz switching frequency to minimize external component size

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring efficient power conversion
• Battery-powered devices needing low quiescent current operation
• Embedded systems utilizing DDR or SRAM termination regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '28X' confirms the fixed 2.8V output voltage configuration. Ensure compatibility with the 6-UFBGA WLCSP package dimensions during PCB layout. Confirm that the -40°C to +85°C industrial temperature rating meets your system's environmental requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V output is required within a 2.3V to 5.5V input window. The 3 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 1 A current limit and WLCSP thermal characteristics for your specific board design constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN53600 series of synchronous buck regulators. It is designed for applications demanding high efficiency and minimal solution size. The series typically includes variants with different fixed output voltages, sharing the same core control architecture and package options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other FAN53600 variants with different output voltage suffixes if 2.8V is not strictly required. Verify pin-to-pin compatibility with alternative suppliers offering similar 3 MHz, 1 A synchronous buck regulators in WLCSP packages.
