ADP2119/ADP2120

Higher or lower inductor and output capacitor values can be

used in the regulator, but the system stability and load transient

performance need to be checked. The minimum output capacitor

is 22 μF for the ADP2119 and 10 μF for the ADP2120, and the

inductor range is 1 μH to 3.3 μH.

A common application is coincident tracking (see Figure 52).

Coincident tracking limits the slave output voltage to be the

same as the master voltage until it reaches regulation. Connect

the TRK pin to a resistor divider from the master voltage. For

coincident tracking, set R_TRKT= R_TOPand R_TRKB= R_BOT

Ratiometric tracking is shown in Figure 53. The slave output is

limited to a fraction of the master voltage. In this application,

the slave and master voltages reach the final value at the same

time. The ratio of the slave output voltage to the master voltage

is a function of the two dividers (see the following equation).

INPUT CAPACITOR SELECTION

The input capacitor reduces the input voltage ripple caused by the

switch current on PVIN. Place the input capacitor as close as

possible to the PVIN pin. A 10 μF or 22 μF ceramic capacitor is

recommended. The rms current rating of the input capacitor

should be larger than calculated by the following equation:

R_TOP

R_BOT

R_TRKT

V_SLAVE

V_MASTER

R_TRKB

I_RMS= I_O× D×(1− D)

VOLTAGE TRACKING

SLAVE

The ADP2119/ADP2120 include a tracking feature that allows

the output (slave voltage) to be configured to track an external

voltage (master voltage), as shown in Figure 51.
