... It provides a ±1% accurate (±3% over all conditions), regulated output voltage with load currents comes in two versions: the ADP2107-1.8-EVAL with fixed output voltage of 1.8 V, and the ADP2107-EVAL with adjustable output voltage initially set to 2.5 V. The ADP2107 is a synchronous, step-down dc-to-dc converter ...

... Insert Jumper J1, and check to see if the output voltage rises to the regulated output voltage (1.8 V for the ADP2107-1.8-EVAL and 2.5 V for the ADP2107-EVAL). If the load is not already enabled, enable the load, and check that it is drawing the proper current and that the output voltage maintains voltage regulation. ...

... I STRING = R4 R5 Note that when the output voltage of the ADP2107-EVAL is changed, the output capacitors (C3 and C4), the inductor (L1), and the compensation components (R1 and C6) must be recalculated and changed according to the Application Information section in the operation. CHANGING THE LOAD TRANSIENT RESPONSE The ADP2107 evaluation board load transient response can be ...
