Specifications subject to change without notice. Note 1: Output voltage ripple can exceed maximum specification during startup when output voltage is less than 0.5V and current is simultaneously greater than 5A. Additional output capacitance will mitigate this startup ripple behavior. For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com) Note 2: Higher values of isolation capacitance can be added external to the module. |
