High switching speeds (tr and tf = 14 ns typ) are obtained with the use of BiCMOS outputs. Typical threshold switching voltages are two-thirds and one-third of VCC. The design inherently minimizes shoot-through current. A regulator is provided on TPS2816 through TPS2819 devices to allow operation with supply inputs between 14V and 40V. The regulator output can be used to power other circuits, provided power dissipation does not exceed package limitations. If the regulator is not required, VDD (the regulator input) should be connected to VCC. The TPS2816 and TPS2817 input circuits include an active pullup circuit to eliminate the need for an external resistor when using open-collector PWM controllers. The TPS2818 and TPS2819 are identical to the TPS2816 and TPS2817, except that the active pullup circuit is omitted. The TPS2828 and TPS2829 are identical to the TPS2818 and TPS2819, except that the internal voltage regulator is omitted, allowing quiescent current to drop to less than 15 µA when the inputs are high or low. The TPS28xx series devices are available in 5-pin SOT-23 (DBV) packages and operate over an ambient temperature range of –40°C to 125°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

However, the large input capacitance (200 pF to 3000 pF or greater) of these devices requires large current surges to reduce the turn-on and turn-off times. The TPS2816 series of high-speed drivers can supply up to 2 A to a MOSFET, greatly reducing the switching times. The fast rise times and fall times and short propagation delays allow for operation in today's high-frequency switching converters. In addition, MOSFETs have a limited gate-bias voltage range, usually less than 20 V. The TPS2816 series of drivers extends this operating range by incorporating an on-board series regulator with an input range up to 40 V. This regulator can be used to power the drivers, the PWM chip, and other circuitry, providing the power dissipation rating is not exceeded. When using these devices, care should be exercised in the proper placement of the driver, the switching MOSFET, and the bypass capacitor. Because of the large input capacitance of the MOSFET, the driver should be placed close to the gate to eliminate the possibility of oscillations caused by trace inductance ringing with the gate capacitance of the MOSFET. When the driver output path is longer than approximately 2 in, a resistor in the range of 10 Ω should be placed in series with the gate drive as close as possible to the MOSFET. A ceramic bypass capacitor also is recommended to provide a source for the high-speed current transients that the MOSFET requires. This capacitor should be placed between VCC and GND of the driver (see Figure 20 and Figure 21). TPS2816 VCC 1 Regulator 5 Load 2 0.1 mF 3 Input 4 Figure 20.

When using the onboard series regulator, an electrolytic output capacitor of 4.7 µF or larger is recommended. Although not required, a 0.1-µF ceramic capacitor on the input of the regulator can help suppress transient currents (see ). When not used, the regulator should be connected to VCC. Grounding VDD results in destruction of the regulator. 34 VDC 0.1 mF + 0.1 mF VCC 4.7 mF TPS2816 PWM Controller 1 Regulator 5 0.1 mF 2 VO Out 3 4 10 mF GND Figure 22. Boost Application The TPS2816 and TPS2818 drivers include active pullup circuits on the inputs to eliminate the need for external pullup resistors when using controllers with open-collector outputs (such as the TL5001). The TPS2817 and TPS2819 drivers have standard CMOS inputs, providing a total device operating current of less than 50 µA. All devices switch at standard CMOS logic levels of approximately two-thirds VCC with positive-going input levels, and approximately one-third VCC with negative-going input levels. Being CMOS drivers, these devices draw relatively large amounts of current (approximately 5 mA) when the inputs are in the range of one-half of the supply voltage. In normal operation, the driver input is in this range for a very short time. Care should be taken to avoid use of very low slew-rate inputs, used under normal operating conditions. Although not destructive to the device, slew rates slower than 0.1 V/µs are not recommended. The BiCMOS output stage provides high instantaneous drive current to rapidly toggle the power switch and very low drop to each rail to ensure proper operation at voltage extremes. Low-voltage circuits (less than 14 V) that require very low quiescent currents can use the TPS2828 and TPS2829 drivers. These drivers use typically 0.2 µA of quiescent current (with inputs high or low). They do not have the internal regulator or the active pullup circuit, but all other specifications are the same as for the rest of the family. 2.5-V/3.3-V, 3-A APPLICATION Figure 23 illustrates the use of the TPS2817 with a TL5001 PWM controller and a TPS1110 in a simple step-down converter application. The converter operates at 275 kHz and delivers either 2.5 V or 3.3 V (determined by the value of R6) at 3 A (5 A peak) from a 5-V supply.
