TPS22965 SLVSBJ0A – AUGUST 2012 – REVISED AUGUST 2013 www.ti.com APPLICATION INFORMATION ON/OFF CONTROL The ON pin controls the state of the switch. Asserting ON high enables the switch. ON is active high and has a low threshold, making it capable of interfacing with low-voltage signals. The ON pin is compatible with standard GPIO logic thresholds. It can be used with any microcontroller with 1.2V or higher GPIO voltage.
PAGE 17
TPS22965 www.ti.com SLVSBJ0A – AUGUST 2012 – REVISED AUGUST 2013 ADJUSTABLE RISE TIME A capacitor to GND on the CT pins sets the slew rate for each channel. The voltage on the CT pin can be as high as 12V. Therefore, the minimum voltage rating for the CT cap should be 25V for optimal performance. An approximate formula for the relationship between CT and slew rate is (the equation below accounts for 10% to 90% measurement on VOUT and does NOT apply for CT = 0pF.
PAGE 18
TPS22965 SLVSBJ0A – AUGUST 2012 – REVISED AUGUST 2013 www.ti.com BOARD LAYOUT AND THERMAL CONSIDERATIONS For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal operation. Using wide traces for VIN, VOUT, and GND helps minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance.
