It can drive the external synchronous rectifier MOSFET for the rectification of the voltage on the secondary winding of the transformer. Figure 3 shows a typical configuration.

TEA1993TS configuration with low-side rectification 8.2 Start-up and UnderVoltage LockOut (UVLO; CAP and XV pins) The capacitor on the CAP pin supplies the TEA1993TS. It is charged via the DRAIN pin when the XV voltage is < 4.7 V. The charge current (Ich(CAP)) charges the capacitor to 4 V. When this voltage is reached, it stops charging. If the external voltage exceeds 4.7 V, the XV pin increases the capacitor voltage via an integrated diode. The increase of the capacitor voltage gives a higher gate driver voltage (VG(max)). When the voltage on the CAP pin exceeds Vstart(CAP) (3.7 V typical), the IC leaves the UVLO state and activates the synchronous rectifier circuitry. When the voltage drops to below 3.6 V (typical), the UVLO state is reentered and the SR MOSFET gate driver output is actively kept low. 8.3 Drain sense (DRAIN pin) The drain sense pin is an input pin capable of handling input voltages up to 120 V. At a positive drain sense voltage, the gate driver is in off-mode with the gate driver pulled down (pin GATE). At a negative drain sense voltage, the IC enables the Synchronous Rectification (SR) by sensing the drain source differential voltage.

All rights reserved. 5 / 20 TEA1993TS NXP Semiconductors GreenChip synchronous rectifier controller 8.4 Synchronous rectification (DRAIN and SOURCE pins) The IC senses the voltage difference between the drain sense (DRAIN pin) and the source sense (SOURCE pin) connections. This drain source differential voltage of the SR MOSFET is used to drive the gate of the SR MOSFET. In the regulation phase, the IC regulates the difference between the drain and the source sense inputs to an absolute level of 37 mV. When the absolute difference exceeds 37 mV (Vreg(drv)), the gate driver output increases the gate voltage of the external SR MOSFET until the 37 mV level is reached. The SR MOSFET does not switch off at low current. To avoid that the device switches off because of ringing, a minimum on-time of 1.5 μs (ttact(sr) (min)) is integrated. When the absolute difference is < 30 mV, the gate driver output decreases the gate voltage of the external SR MOSFET. The voltage waveform on the SR MOSFET gate follows the waveform of the current through the SR MOSFET. When the current through the SR MOSFET reaches zero, the SR MOSFET is quickly switched off. After SR MOSFET switch-off, the drain voltage increases. When the drain voltage exceeds 300 mV, a low ohmic gate pull-down of 7 Ω keeps the gate of the SR MOSFET switched off. 8.5 Gate driver (GATE pin) The gate driver circuit charges the gate of the external SR MOSFET during the rising part of the current. The driver circuit discharges the gate during the falling part of the current. The gate driver has a source capability of typically 0.50 A and a sink capability of typically 0.65 A, allowing fast turn-on and fast turn-off of the external SR MOSFET. The maximum output voltage of the driver is limited to 12 V. This high output voltage drives all MOSFET brands to the minimum on-state resistance. In applications where the IC is supplied with 5 V, the maximum output voltage of the driver is 4.2 V and logic level SR MOSFETs can be used (see Figure 3). The IC is self-supplying in applications with high-side rectification or in battery charging applications with an output voltage below 4.7 V. When the XV pin is connected to ground for driving standard SR MOSFETs, the driver is regulated to 9 V. When the XV pin is connected to the converter output for driving logic-level SR MOSFETs, the driver is regulated to 4 V if the output voltage is below 4.7 V.

Maximum gate voltage VG(max) During start-up conditions (VCAP < Vstart(CAP)) and UVLO, the driver output voltage is actively pulled low. 8.6 Source sense (SOURCE pin) The IC is equipped with an additional source sense pin (SOURCE). This pin is used for measuring the drain-to-source voltage of the external SR MOSFET. The source sense input must be connected as close as possible to the SOURCE pin of the external SR MOSFET. It minimizes errors, caused by voltage differences on PCB tracks due to parasitic inductance in combination with large dI/dt values.

To obtain low conduction loss rectification, an SR MOSFET is used in the output stage. The SR MOSFET can be placed low-side (see Figure 3) or can be placed high-side (see Figure 11). In the high-side application, the TEA1993TS is self-supplying. The capacitor on the CAP pin supplies the TEA1993TS. When the drain voltage is positive, it is charged via the DRAIN pin. The gate drive voltage for the synchronous rectifier switch is derived from the voltage difference between the corresponding drain sense and source sense pins. Special attention must be paid to the connection of the drain sense and source sense pins. The voltages measured on these pins are used for the gate drive voltage. Wrong measurement results in a less efficient gate drive because a gate voltage that is either too low or too high. The connections to these pins must not interfere with the power wiring. The power wiring conducts currents with high dI/dt values. It can easily cause measurement errors resulting from induced voltages due to parasitic inductances. The separate source sense pins make it possible to sense the source voltage of the external MOSFETs directly. So, the current carrying power ground tracks are not required.
