Application information A resonant switched mode power supply with the TEA1995T consists of a primary side half-bridge, a transformer, a resonant capacitor, and an output stage. To obtain low conduction loss rectification, SR MOSFETs are used in the output stage. The TEA1995T controls these SR MOSFETs. The gate drive voltage for the SR 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 gate drive voltage. Wrong measurement results in a less efficient gate drive because the gate voltage 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 enable the direct sensing of the source voltage of the external MOSFETs. Using the current carrying power ground tracks is not allowed. 11.1 Application diagram resonant application Fig 5. Typical resonant application with TEA1995T |
