UCC3880
The UCC3880 PWM controller shown in Figure 25 combines a
switch-mode DC-to-DC controller with a reference DAC, and a
precision reference in a single package. The accuracy of the
DAC/reference combination is 1.0%. Typical efficiency is
greater than 83% at 11.2A. The DAC provides a mechanism to
adjust the DC-to-DC converter output between 2.1V and 3.5V
in 100 mV steps. Over-voltage and under-voltage monitors are
also included. Table 19 on page 52 shows the bill of materials
for the UCC3880 capable of up to 16 A.
