The negative charge pump starts with a soft start and when the output voltage has reached 91% of the nominal value, the positive charge pump comes up with a soft start. The VCOM buffer is enabled as soon as the positive charge pump has reached its nominal value and VCOMIN is greater than typically 1.0 V. Pulling the enable pin low shuts down the device.

TPS65100, TPS65101 TPS65105 www.ti.com SLVS496C – SEPTEMBER 2003 – REVISED APRIL 2006 DETAILED DESCRIPTION (continued) Thermal Shutdown A thermal shutdown is implemented to prevent damage due to excessive heat and power dissipation. Typically, the thermal shutdown threshold is 160°C. If this temperature is reached, the device goes into shutdown. The device can be enabled by toggling the enable pin to low and back to high or by cycling the input voltage to GND and back to VI again.

TPS65100, TPS65101 TPS65105 www.ti.com SLVS496C – SEPTEMBER 2003 – REVISED APRIL 2006 APPLICATION INFORMATION BOOST CONVERTER DESIGN PROCEDURE The first step in the design procedure is to calculate the maximum possible output current of the main boost converter under certain input and output voltage conditions. The following example is for a 3.3-V to 10-V conversion: Vin = 3.3 V, Vout = 10 V, Switch voltage drop Vsw = 0.5 V, Schottky diode forward voltage VD = 0.8 V 1.

A small feedforward capacitor across the upper feedback resistor divider speeds up the circuit as well.

Load Step Caused By A Too Large Feedforward Capacitor Value Compensation The regulator loop can be compensated by adjusting the external components connected to the COMP pin. The COMP pin is connected to the output of the internal transconductance error amplifier. A typical compensation scheme is shown in Figure 17. RC 15 kΩ CC VIN COMP 1 nF Figure 17.

TPS65100, TPS65101 TPS65105 www.ti.com SLVS496C – SEPTEMBER 2003 – REVISED APRIL 2006 Figure 19. Cc = 1 nF Lastly, Rc needs to be selected. A good practice is to use a 50-kΩ potentiometer and adjust the potentiometer for best load transient where no oscillations should occur. These tests have to be done at the highest Vin and highest load current because converter stability is most critical under these conditions. Figure 20, Figure 21, and Figure 22 show the fine tuning of the loop with Rc. Figure 20.

The negative charge pump output voltage is set with external feedback resistors.

The VCOM output voltage is typically set to half of the main output voltage VO1 plus a small shift to implement the specific compensation voltage.
