In a project customization, clients asked us to make the CPU main-controlled and LCD displays a single ballast power-driven circuit, and the LCD displays AVDD, VGH, VGL, etc. for the screens, which are provided by the main control board, because the electric ballasts exported are small (normally more than 10 mA, which is specifically accessible to the screen manual) and can be used for the jet pumping circuit. Here, I am sharing a chip programme for integrated pumps, using TITPS65140, the following is a road map, which has some scope of application restrictions, which I will say below.

This information is based on the tps65140 chip manual from TI, the Application SLVA918-27December 2017 and the HSP202E chip manual from maxim.

TPS6510x and TPS6514x contain power circuits for active power pumps and negative power pumps. For pumps, these equipment is integrated into two potassiums requiring external connections. Within the limits available for the export of electric pressure, the equipment may regulate the export pressure of the charge pump.

Most of the application circuits use the level I charge pumps as shown in figure 1. More than one level could be used to generate more negative power pressure, but few LCDs needed such a negative pressure and were therefore not discussed here.

The smallest (i.e. the most negative) of the power route is given below:

Figure 2 is the range of power-outs that can be generated by a negative power pump in a device, a function of PV1.

If an attempt is made to generate less than the available power of export, the bottom border of the grey region is to export the pressure. For example, if VO1 = 11 V, and if you try to generate VO2 = 12 V, you will receive approximately - 9.7V (to be found by following the bottom line of VO1 = 11 V until the grey area is reached). In other words, the minimum value of negative pressure is limited by VO1.

In order to correctly use the double-folding configuration of the main pump, the electrical container is connected to the two ends of the C1- and C1+. Maintaining the road to entry C2+, as shown in figure 3.

The biggest export pressure that can be generated by a two-folder is given below:

The smallest export pressure of the multi-frequency device is given in the bottom:

The electrical pressure from the electrical pumps is also limited to VO1, the scope of which is shown below. If VO1 = 11 V, and if you try to produce VO3 = 24 V using double-load pumps, only about 20.6 V (subject to VO1 = 11 V gigabytes up to the top boundary in grey areas).

If VO3 pressure is higher than that generated by double-load pumps, please use the three-fold configuration shown in figure 4. An additional transmissible trans-mechannel will be connected between quoted C2-/ Mode and C2+.

The maximum output pressure of three times the electric circuit is given in the lower format.

The maximum value of VO3 is 30V.

Minimized export pressure is given in the bottom

The electrical pressure from the electrical pumps is also limited to VO1, the scope of which is shown below. If VO1 = 11 V, you tried to produce VO3 = 16 V with a threefold charge pump, you would find it in the red filling area. As a result, the equipment will be reconciled to the minimum value of approximately 20V (subject to VO1 = 11 V line until red line).

The charge pumps in TPS65140 can regulate the export of electric pressure and the curable pressure is of some scope and can be viewed in the present file as to the range of exportable pressure available for the device. If applied close to the periphery of the permissible range, please ensure that design is sufficient to function properly under all conditions.

In order to better help better understand the rationale of the pump, the internal structure of the TTL-RS232 chip can be more visible. The typical PVx2xx series of electrical switches is based on a single power +5V power supply, with a charge pump to generate ±10V pressure for RS232.

Typically, four sets of electrical appliances are used, with double-load pumps, as follows:

The self-sustaining cranes in the chip drives two-load pumps, working in two-steps, as follows:

VCC + 5V power. V+ and V - respectively, export pump pressure.

First step: S1, S3 closed, S2, S4 interrupted, U5V supplied C1 with electricity up to 5V.

Second step: S2, S4 closed, S1, S3 cut off, when the negative end-point of the C1 should be equal to the +5 V, the C1 storage power load transferred from S2, S4 to C3, the C3 pressure margin should be 5V and the V+ power source VCC combined to provide 10V.

Third step: S5, S7 closed, C3 storage chargeable to C2 and C2 pressure up to 10V.

The second and third steps are actually taken simultaneously.

Fourth step, S6, S8 closed, C2 stored electric pressure transferred from S6, S8 to C4, C4 maximum power to 10V, such as the method of transmission in the map, constituted a counter-wireless pump, providing V-10V.
