DESCRIPTION
NAME
QFN
TSSOP
Gate voltage shaping circuit. Connecting a capacitor to this pin sets the fall time of the
positive gate voltage (VGH).
This is the compensation pin for the main boost converter. A small capacitor and if required
a series resistor is connected to this pin.
Input of the VGH isolation switch and gate voltage shaping circuit.
Control signal for the gate voltage shaping signal. Apply the control signal for the gate
voltage control. Usually the timing controller of the LCD panel generates this signal. If this
function is not required, this pin needs to be connected to VIN. By doing this, the internal
switch between CPI and VGH provides isolation for the positive charge pump output VGH.
DLY2 sets the delay time for VGH to come up.
Power-on sequencing adjust. Connecting a capacitor from this pin to GND allows to set the
delay time between the boost converter output Vs and the negative charge pump VGL
during startup.
Power-on sequencing adjust. Connecting a capacitor from this pin to GND allows to set the
delay time between the negative charge pump VGL and the positive charge pump during
startup. Note that Q5 in the Gate Voltage Shaping block only turns on when the positive
charge pump (FBP) is within regulation. (This provides input to output isolation of VGH).
Charge pump driver to generate the negative voltage VGL.
Charge pump driver to generate the positive output voltage VGH.
Feedback of the main boost converter generating Vsource (Vs).
Feedback pin of the negative charge pump VGL.
Feedback pin of the positive charge pump.
Fault delay. Connecting a capacitor from this pin to Vin allows to set the delay time from
the point when one of the outputs (VS, VGH, VGL) drops below its power good threshold
until the devices enters the shutdown latch. To re-start the device the input voltage has to
be cycled to GND. This feature can be disabled by connecting the FDLY pin to Vin.
Active low open drain output. This output is latched low when the boost converter Vs is in
regulation. This signal can be used to drive an external MOSFET to provide isolation for Vs.
