The V
remove flicker. The ISL45042A can be used to digitally
adjust a panel’s V
current. The output of the ISL45042A is connected to an
external voltage divider and an external V
amplifier. In this application, the user can control the V
voltage with 7-bit accuracy (128 steps). Once the desired
V
non-volatile EEPROM memory, which would then be
automatically recalled during every power-up.
The V
programming is through a single interface pin (CTL). Once
the desired programmed value is obtained, the Counter
Enable pin (CE) can be used to prevent further adjustment
or programming.
The full-scale sink current of the ISL45042A is set using an
external resistor connected to the SET pin. The full-scale
sink current determines the lowest voltage of the external
voltage divider.
The ISL45042A is available in an 8 Ld 3mmx3mm TDFN
package with a maximum thickness of 0.8mm for ultra thin
LCD panel design.
