In order to increase the Vout as much as possible up to 5.2 V a Schottky diode must be placed between the

Lx and Vout pins, as shown in Figure 2.

Given Tj = Ta + RthJA x PD, and assuming RthJA = 135°C/W, and that in order to avoid device destruction

Tjmax must be

≤ 125 °C, and that in the worst conditions T

A = 85 °C, the power dissipated inside the

device is given by:

Therefore, if in the worst case the efficiency is assumed to be 90%, then PIN-MAX = 3.3 W and POUT-MAX = 3 W.
