Description

This is TFT-LCD 3-Channel Charge Pump Power IC. A charge pump power IC (Integrated Circuit) is a semiconductor device designed to generate and regulate output voltages from an input voltage source by using charge-pumping techniques. Charge pumps are used to increase or decrease voltage levels, depending on the specific application.

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 NT-50198 can provide a suitable and stable voltage level to TFT LCD driver IC, and NT50198 can refer to PSYNC signal to switch from charge state to pump state and vice versa. This function can avoid state changing noise to interfere display quality. If the driver IC or baseband can not provide PSYNC, please connect PSYNC signal to GND pin for free-running mode (Internal frequency =125 KHz). […]

Pinouts:

Features

1. Charge pump x2 mode for positive AVDD and x-1 mode for negative AVEE .

2. Charge pump clock synchronized with PSYNC for benefit of low noise.

3. Positive and Negative regulated charge Pump with Diode free.

4. External Capacitor 5C or 7C only

Description

LD40044APG is 4.00 inch 4×4 Dot Matrix LED Display. This is a type of electronic display device that consists of an array of individual light-emitting diodes (LEDs) organized in a rectangular matrix or grid, with each LED representing a pixel.

These displays are used to show alphanumeric characters, symbols, and even simple graphics by selectively turning on or off specific LEDs within the matrix. Dot matrix LED displays are commonly used in a wide range of applications, including electronic signs, information boards, scoreboards, and message displays.

Features

1. 108.80 mm (4.00 inch) digit high

2. Dot size : Diameter 20.00 mm

3. Pitch : 27.20 mm

4. Wide viewing angle

5. Range of emitted colors

6. I.C. compatible

7. Low power consumption

8. White dot, grey or black face
