FAN602FZMX is listed in the AC DC Converters, Offline Switchers range at ChipApex. The manufacturer field lists Fairchild Semiconductor. Its product description is FAN602 - SWITCHING CONTROLLER. Review the specifications below when checking this part for your BOM.
The FAN602FZMX is an offline switching controller manufactured by Fairchild Semiconductor, designed for quasi-resonant flyback converter topologies. It operates within a switching frequency range of 50 kHz to 150 kHz and features a fixed output voltage of 7.5 V. The device supports surface-mount installation in an SOIC-10 package and functions reliably across a temperature range of -40°C to +125°C. Key electrical characteristics include a typical rise time of 135 ns and fall time of 50 ns, with a maximum operating supply current of 2 mA at 15 V.
Verify the manufacturer designation carefully, as Fairchild Semiconductor operations have been integrated into onsemi. Confirm that the specific suffix 'FZMX' corresponds to the required packaging format and ensure compatibility with current component sourcing channels given potential corporate restructuring impacts on part availability and documentation access.
Select this component when designing offline converters requiring variable frequency operation between 50 kHz and 150 kHz. Ensure the design accommodates the SOIC-10 package constraints and verify that the 7.5 V internal reference aligns with the target feedback loop requirements. Consider the extended temperature range if the application involves harsh environmental conditions.
This component belongs to the FAN602 series of power management ICs focused on efficient AC/DC conversion. It serves as a core control element in switch-mode power supplies, replacing older fixed-frequency controllers to improve overall system efficiency through resonant switching techniques.
