1. General Description
NT50198
The NT50198 is a high-performance step-up charge pump and inverter to generate two output voltages; it is
including pumping controllers for positive and negative output voltage. The following content contains the detailed
description and the information of component selection.
The positive charge-pump controller provides adjustable regulated output AVDD and fixed -1 ratio of AVEE to
supply the TFT.
The pumping clock can be generated by internal circuit, to reduce the control signal from driver IC. Or the
charge and pump state can be synchronized with LCD display TE signal (PSYNC), it can reduce the interference to
display quality when states change.
The device requires only five (12 pins) or seven (16 pins) small and low-cost ceramic capacitors.
NT50198 is available in TDFN-12 / TDFN-16 / QFN-16 pins package for smart phone LCD panel’s driver IC.
Note: According to the FPC layout experience, the components on the FPC may have chance to fall off when
wind the FPC. So we strongly suggest to add the Stiffener under the FPC backside area of NT50198.
2. Features
Charge pump x2 mode for positive AVDD and x-1 mode for negative AVEE .
2.5V to 4.8V input supply voltage range
AVDD output range 5.8V to 6.0V.
AVEE output range -5.8V to -6.0V.
VCL output range -2.5V to -3.2V.
Charge pump clock synchronized with PSYNC for benefit of low noise.
Positive and Negative regulated charge Pump with Diode free.
External Capacitor 5C or 7C only.
QFN-16 (3.0mm * 3.0mm * 0.8 mm) package is available.
TDFN-12 (1.5mm * 2.4mm * 0.5 mm) package is available.
TDFN-16 (1.5mm * 3.2mm * 0.5 mm) package is available.
