TEA1905: USB-PD type C controller for SMPS

The TEA1905 is a USB Power Delivery (USB-PD) type-C and other proprietary protocol (Quick Charge) controller with a high integration level and near fully digital bare minimum of external components. The TEA1905 USB-PD controller drives an NMOS load switch. It achieves a very high power density Switching Mode Power Supply (SMPS) with an ultra-high efficiency over the entire load range. When applied in combination with the NXP Semiconductors primary controller, TEA1936T, it meets the CoC Tier-2, EuP lot 6, and DOE v6 energy efficiency requirement specifications.

In addition to the power control and required protections, the TEA1905 incorporates the full feature set of the type C USB-PD protocol that is required for an AC-to-DC SMPS adapter.

The SW pin is used to drive an external load switch (NMOS), which enables/disables the power over Vbus. When the output voltage is reduced or the type-C cable is detached, the DISCH pin ensures that the output voltage discharges in a controlled way to the voltage level required by the USB-PD protocol.

The TEA1905 incorporates all required protections, like OverTemperature Protection (OTP), adaptive OverVoltage Protection (OVP), Short Circuit Protection (SCP), and UnderVoltage LockOut (UVLO) protection.

  • High integration level (only requires an external line switch and SR diode or controller)
  • NMOS load switch without external winding
  • Fault handling at secondary side without second optocoupler
  • Low-cost SO14 package (suitable for both reflow soldering and wave soldering) or leadless HVSON16 package for smaller size (reflow only)
  • Low-cost Bill Of Materials (BOM; ≈15 external components)
  • Very low no-load power (< 25 mW for the complete system solution)
  • High power density
  • Ultra-high efficiency
