4-Channel DC/DC Controller

Features

• Complete TFT-LCD supply controller

- 1MHz PWM boost controller

EL7520 and EL7520A are 4-channel DC/DC controllers that

provide a complete power supply system for TFT-LCD

applications. They consist of a 1MHz PWM boost controller,

which generates the main voltage for the column driver, and

EL7520 and EL7520A operate from 3V to 5.5V. The boost

controller can drive a wide range of output current

depending on the external FET. It can be programmed to

operate in either P-mode for fast transient response or PI-

mode for improved load regulation. The EL7520 and

EL7520A also integrate fault protection for all four output

channels. When a fault is detected, the device is latched off

until either the input supply voltage or enable is cycled.

Therefore, they are ideal to use in any size of TFT-LCD

panels.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
