16V Pico TLynx^TM 4A: Non-isolated DC-DC Power Modules
8 – 16Vdc input; 0.6Vdc to 8.0Vdc output; 4A output current
common output voltages in the presence of a 2A to
4A step change (50% of full load), with an input
voltage of 16V.
Please contact your Lineage Power technical
representative to obtain more details of this feature as
well as for guidelines on how to select the right value
of external R-C to tune the module for best transient
performance and stable operation for other output
capacitance values or input voltages other than 16V.
