use typical values of V IN and f SW so that efficiency is opti-
mum for typical conditions. The switching frequency (f SW )
is fixed at 135kHz (MAX5096) and 330kHz (MAX5097).
CURRENT IS CRITICAL.

Selection
f SW can also be varied from 120kHz to 500kHz
(MAX5096) and from 300kHz to 500kHz (MAX5097) when
synchronized to an external clock (see the Oscillator/
Synchronization Input (SYNC) section). The peak-to-peak
inductor current, which reflects the peak-to-peak output
ripple, is worst at the maximum input voltage. See the
Output Capacitor Selection section to verify that the
worst-case output ripple is acceptable. The inductor satu-
rating current (I SAT ) is also important to avoid runaway
current during continuous output short circuit. Select an
inductor with an I SAT specification higher than the maxi-
mum peak current limit of 1.9A.
The Buck Mode operation determines the inductor and
output capacitor values. However, the values of the
inductor, its DCR, and the output capacitance/ESR
affect the closed-loop transfer function both in Buck
and LDO Modes. The internal compensation of the

MAX5096/MAX5097 in LDO Mode limits the values of
these external components. Make sure that the combi-
nation of output inductor, capacitor, and ESR falls with-
in the range specified in following Table 1.
Output Capacitor Selection
The allowable output voltage ripple and the maximum
deviation of the output voltage during load steps deter-
mine the output capacitance and its ESR. The output
