Figure 1. Typical Operating Circuit

Typical Operating Circuit

The typical operating circuit (Figure 1) of the

MAX17075 is a complete power-supply system for TFT

LCD panels in monitors and TVs. The circuit generates

a +13V source driver supply, a +30V positive gate-dri-

ver supply, and a -7V negative gate-driver supply from

a +2.5V to +5.5V input supply. Table 1 lists some

selected components, and Table 2 lists the contact

information for component suppliers.
