FAN65004C

Voltage Regulators - DC DC Switching Regulators Overview

The FAN65004C is a synchronous PWM buck regulator from onsemi, designed for high-performance voltage mode control. It operates with an input voltage range of 4.5 V to 65 V and supports a maximum output current of 6 A. The device features adjustable switching frequencies ranging from 100 kHz to 1 MHz and includes input voltage feed-forward for improved transient response. It integrates a wide array of protection circuits, including over-current protection (OCP), thermal shutdown (TSD), over-voltage protection (OVP), under-voltage protection (UVP), and short-circuit protection (SCP).

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., 'C') against official datasheets to confirm pinout and electrical characteristics, as variations may exist within the FAN65004 family. Ensure compatibility with the Strata Development Environment if utilizing evaluation boards like the STR-FAN65004C-GEVB for performance testing. Confirm package availability and lead times through authorized distributors, as supply chain conditions fluctuate.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select the FAN65004C when an input voltage up to 65 V is required, distinguishing it from lower-voltage variants in the same series. Choose this component for applications needing precise voltage mode control with feed-forward capabilities. Consider the adjustable frequency range for optimizing EMI and efficiency trade-offs. Verify that the 6 A current rating meets the load requirements and that the integrated protection features align with system safety standards.
