PQ60050EGL15 ELECTRICAL CHARACTERISTICS

perature with appropriate power derating. Specifications subject to change without notice.

Note 1: The UVLO values represented here are typical of lighter load conditions. The unit may shut down under high load conditions before the typical UVLO limits.

Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)

Note 3: The module requires a minimum amount of capacitance (100µF) in order to ride through a No Load to Full Load transient (0.1A/µs) without shutdown.

Note 4: Higher values of isolation capacitance can be added external to the module.
