Applications Information
The EL7585 is a highly integrated multiple output power
solution for TFT-LCD applications. The system consists of
one high efficiency boost converter and three linear-
regulator controllers (V
ON
, V
OFF
, and V
LOGIC
) with multiple
protection functions. A block diagram is shown in Figure 20.
Table 1 lists the recommended components.
The EL7585 integrates an N-channel MOSFET boost
converter to minimize external component count and cost.
The A
VDD
, V
ON
, V
OFF
, and V
LOGIC
output voltages are
independently set using external resistors. V
ON
, V
OFF
voltages require external charge pumps which are post
regulated using the integrated LDO controllers.
