APPLICATION CIRCUIT FOR TPS65111
DESCRIPTION
The TPS65110/11 is a very compact power supply
solution providing the three voltages required by many
LTPS LCD displays.
All three regulated outputs are generated using a charge
pump topology.
The VCC charge pump provides precise, high efficiency,
and very low ripple dc/dc conversion for the LCD analog
power. The VCC boost ratio (x1.0, x1.33, x1.5, and x2.0)
is automatically set based on input and output voltage
conditions. The VCC output assures 16 mA of current by
using three 0.22-
μ
F flying capacitors. If the required output
current is smaller, smaller capacitors can be applied.
The VDD
charge pump provides a higher positive voltage,
and the VSS charge pump provides the negative output
voltage. Power up/down sequences are internally set and
are secured even in cases of sudden and abnormal VIN
drop.
One of the most significant features of the TPS65110/11
is the ultra-low output voltage ripple, as the VCC charge
pump achieves 5-mV output ripple voltage.
