Maxim
MAX798
The MAX798 current-mode converter shown in Figure 19
converts the input voltage (from the wall adapter or the battery
pack) down to the desired 1.8V. The MAX798 can achieve
efficiencies up to 96% and has an input-voltage rage of 4.5V to
30V. The input voltage is switched by the MOSFETs N1 and N2.
This switched voltage is filtered by the LC filter, consisting of
L1, C4, and C5. R1 and R2 divide the 1.8V output voltage to
1.6V for the feedback reference (Vout = 1.6V
·
(1 + R1/R2). The
values in the bill of material (See Table 10 on page 39) provide
1.8V at 5.6A. The 560-pF capacitor improves stability by
increasing the loop phase at crossover, which increases the
phase margin.
Maxim’s MAX1710/11 has VID inputs.
