4-Channel DC/DC 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
three LDO controllers for V ON , V OFF , and V LOGIC supplies.
They also include integrated start-up sequence and start-up
delay control.
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.
The EL7520 and EL7520A are available in a 20 Ld 4x4 QFN
package with maximum height of 0.9mm and is specified for
operation of the -40°C to +85°C temperature range.
