Please let me know about DCP020505 Vout and test circuit.

Other Parts Discussed in Thread: DCP020505

When DCP020505 was tested, Vout became higher than a data sheet.
If the portion which causes a high-Vout with an attached circuit diagram, and a mistake occur, please let me know.

A circuit is parallel, and is using two devices and an input is set to 5V.

A test result is the following.

No load --- 5.74V

100Ω --- 5.64V (56mA)

50Ω --- 5.57V (111mA)

33Ω --- 5.51V (172mA)

22Ω --- 5.41V (246mA)

 

※I am sorry for a circuit diagram hard to see.
Please contact me, if there is information which is not known.

    DCP020505 is an unregulated converter. The output voltage varies with changes to output voltage( Vout)  load  and input line voltage(Vin) for each converter. .

    The output voltage  range for each DCP020505 is  determined by both vin and vout load.:

    Defined output voltage at 75% load for (1) DCP020505  is: (each separate DCP20505 with 5V0  +/-0.5% input voltage  and 75% load  (1.5W  at  300mA) , the output voltage range is 4.75V to 5.25V.

    1. The load for two(2) parallel DCP020505 with exactly 5V0 +/-0.5% input voltage to meet the typical Vout (5V0+/-5%) at 75% current  load range is typically 400mA to 625mA .
