Introduction WARNING Lethal voltage and fire ignition hazard The non-insulated high voltages that are present when operating this product, constitute a risk of electric shock, personal injury, death and/or ignition of fire. This product is intended for evaluation purposes only. It shall be operated in a designated test area by personnel qualified according to local requirements and labor laws to work with non-insulated mains voltages and high-voltage circuits. This product shall never be operated unattended. This user manual describes the application of the TEA1721ADB1062 demo board. The demo board is designed as an isolated 24 V, 5 V and 3.3 V AC/DC SMPS for supplying up to 5 W to a load. On the input side, single phase, 2-phase or 3-phase Universal Mains power can be connected. The switch-mode converter operates in flyback mode at a maximum frequency of around 50 kHz. Overcurrent and short-circuit protection are built in. The power consumption is below 50 mW under no-load conditions. EMI filtering and surge protection using TVS diodes is implemented in this circuit. This application is intended as a 3-phase low-power SMPS which is especially suited for 3-phase industrial and multi-phase e-metering SMPS applications. Do not exceed an RMS input voltage of 560 V (AC) across any combination of the J1.x connectors. 560 V (AC) corresponds to a maximum instantaneous voltage difference of 800 V. An additional high surge protection using MOVs can be implemented if necessary. 1.1 Features and benefits • • • • • • • UM10520 User manual Compatible with 3-phase universal mains Tolerant with respect to “missing neutral” Inrush current limitation EMI filtering to meet EMC requirements of EN55022 ESD protection on the TEA1721 Optional high-surge protection companion circuit option Power Line Communication (PLC) decoupling extension All information provided in this document is subject to legal disclaimers.

The secondary winding must have a tap for the 5 V and the 3.3 V output voltage. The magnetic coupling between the secondary and the auxiliary winding must be optimal. [2] To set the output voltage with greater accuracy, fine-tuning is required. UM10520 User manual All information provided in this document is subject to legal disclaimers.

Optional modifications implementation guidelines • The output voltages are adjusted using resistors R11 and R15. The secondary winding on transformer T1 turns ratio defines the ratio between the three output voltages. Using a different transformer makes other output voltages and/or other output voltage ratios available. • To achieve good voltage regulation, the secondary winding and the auxiliary winding of the transformer must have a tight magnetic coupling. • The maximum output power and output current levels are adjusted using resistor R14. The maximum current allowed in the TEA1721 IC switching MOSFET is 700 mA. Take care that under no circumstances, the peak current in the primary winding of the T1 transformer exceeds 700 mA. • Resistors R1, R2, R3 and R4 limit the inrush current. The resistor must be a carbon resistor because metal film resistors can act as a fuse in this position. If no inrush current limiting is required, the resistor can be replaced with a short-circuit. • EMI-filtering is implemented using separate stages for common mode (L1) and differential mode (L2). Depending on the requirements, the filtering stage can be adapted. For example, inductor L1 can be chosen to ensure that its leakage inductance takes care of differential filtering. As a consequence L2 can be omitted. • Surge voltage protection is implemented using TVS diodes D9, D10, D11, D12 and capacitors C5/C6. The surge protection limits the DC bus voltage to 800 V. The TVS diodes choice determines the maximum allowable surge pulse energy. • Resistors R17, R18 and R19 form small pre-loads for the converter. When the output voltages are adjusted, also adjust the pre-load resistors to ensure that they consume roughly the same amount of power. Depending on the connected load, eliminate the resistors. • Zener diodes D21, D22 and D23 are an elementary output OverVoltage Protection (OVP). When OVP is not needed, eliminate the diodes. • Capacitors C11, C13 and C15 are used to obtain additional (HF) voltage stability and noise suppression. Eliminate the capacitors when the feature is not needed. • Capacitor C16 is a Y-capacitor. If theT1 transformer construction provides the required EMI performance without the use of capacitor C16, omit the capacitor. • Additional high surge protection using MOVs (V1 to V4) is implemented using the dedicated companion circuit in the front end. Depending on the application requirements, fuses (F1 to F4) can be included in the circuit as required. The MOVs must be DC rated at approximately 400 V. For example, S10K320. • Additional Power Line Communication (PLC) decoupling can be implemented when the SMPS is used in combination with a PLC transceiver module. For example in e-metering applications. Depending on the frequency band, choose the value for L1.1 to L1.4. Typically, the inductor values range between a few hundred µH up to several mH.
