FAN7529M

Overview

The FAN7529M is a boundary mode power factor correction (PFC) controller manufactured by onsemi. It operates within a supply voltage range of 9.5 V to 25 V and supports a maximum output current of 0.5 A. The device utilizes pulse width modulation (PWM) control technology and functions as a combined power factor and fluorescent light controller. It is housed in an SOP-8 package with a body length of 4.9 mm. The component is designed for operation across a temperature range from -25 °C to +125 °C.

Feature Summary

Integrates boundary mode PFC control with fluorescent lighting capabilities
Employs pulse width modulation for precise regulation
Supports wide input voltage ranges up to 25 V

Applications

Power factor correction circuits
Fluorescent lamp ballast systems
Combined power management IC designs

Procurement Notes

Verify the specific suffix 'MX' or 'M' against official datasheets, as packaging formats may differ. Confirm RoHS compliance status directly with manufacturer documentation. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when boundary mode PFC control is required alongside integrated lighting functions. Ensure the operating environment stays within the specified -25 °C to +125 °C temperature limits. Verify that the SOP-8 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the family of mixed-signal controllers combining power conversion and lighting drive functions. It serves applications requiring efficient power factor correction in conjunction with discharge lamp technologies. The design targets compact solutions where space efficiency and functional integration are critical.

Replacement Considerations

Consult official substitution guides for compatible boundary mode PFC controllers. Verify pinout compatibility and electrical specifications before replacing existing units.
