FAN5660IM

Voltage Regulators - DC DC Switching Regulators Overview

The FAN5660IM is a synchronous buck controller designed for high-efficiency power conversion. It integrates two N-channel MOSFET drivers and operates with an input voltage range of 4.5V to 28V. The device supports adjustable output voltages down to 0.8V via an external resistor divider. Key electrical parameters include a switching frequency up to 1MHz, selectable from internal or external clocks. It features programmable soft-start and current limit protection. The component is housed in a 16-lead TSSOP package with exposed pad for thermal dissipation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer source carefully as Fairchild Semiconductor has undergone corporate restructuring and integration into onsemi. Ensure the ordering part number matches the specific suffix required for your packaging needs. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary due to product lifecycle changes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing synchronous buck converters requiring high efficiency and compact footprint. Consider the 16-lead TSSOP package for PCB space constraints. Evaluate the thermal performance requirements given the exposed pad design. Ensure the input voltage range aligns with your system's supply rails and that the output voltage requirements fall within the supported adjustment range.

Voltage Regulators - DC DC Switching Regulators Part Context

This controller belongs to the family of synchronous buck converter ICs used in modern power management applications. It replaces older asynchronous designs by integrating both high-side and low-side drive capabilities, reducing external component count and improving overall system efficiency. The device is engineered for stable operation under varying load conditions typical in digital logic power supplies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the same manufacturer portfolio or compatible alternatives from other vendors offering similar synchronous buck controllers. Verify that any substitute maintains the same operating voltage range, switching frequency characteristics, and protection feature set to ensure circuit compatibility without redesign.
