TEA1623P; TEA1623PH STARplug switched mode power supply controller IC Rev. 3 — 30 August 2010 Product data sheet 1. General description The TEA1623 is a Switched Mode Power Supply (SMPS) controller IC that operates directly from rectified universal mains. It is implemented in the high voltage EZ-HV SOI process, combined with a low voltage BiCMOS process. The device includes a high voltage power switch and a circuit for start-up directly from the rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible. In its most basic version of application, the TEA1623 acts as a voltage source. Here, no additional secondary electronics are required. A combined voltage and current source can be realized with minimum costs for external components. Implementation of the TEA1623 renders an efficient and low cost power supply system. 2.

Functional description The TEA1623 is the heart of a compact flyback converter, with the IC placed at the primary side. The auxiliary winding of the transformer can be used for indirect feedback to control the isolated output. This additional winding also powers the IC. A more accurate control of the output voltage and/or current can be implemented with an additional secondary sensing circuit and optocoupler feedback. The TEA1623 uses voltage mode control. The frequency is determined by the maximum transformer demagnetizing time or the frequency of the oscillator. In the first case, the converter operates in the Self Oscillating Power Supply (SOPS) mode. In the latter case, it operates at a constant frequency, which can be adjusted with external components RRC and CRC. This mode is called Pulse Width Modulation (PWM). Furthermore, a primary stroke is started only in a valley of the secondary ringing. This valley switching principle minimizes capacitive switch-on losses. 8.1 Start-up and UnderVoltage LockOut (UVLO) Initially, the IC is self supplying from the rectified mains voltage. The IC starts switching as soon as the voltage on pin VCC passes the VCC(start) level. The supply is taken over by the auxiliary winding of the transformer as soon as VCC is high enough and the supply from the line is stopped for high efficiency operation. As soon as the voltage on pin VCC drops below the VCC(stop) level, the IC stops switching and restarts from the rectified mains voltage. 8.2 Oscillator The frequency of the oscillator is set by the external resistor and capacitor on pin RC. The external capacitor is charged rapidly to the VRC(max) level and, starting from a new primary stroke, it discharges to the VRC(min) level. Because the discharge is exponential, the TEA1623P_TEA1623PH Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 3 — 30 August 2010 © NXP B.V. 2010. All rights reserved. 5 of 20 TEA1623P; TEA1623PH NXP Semiconductors STARplug switched mode power supply controller IC relative sensitivity of the duty factor to the regulation voltage at low duty factor is almost equal to the sensitivity at high duty factors. This results in a more constant gain over the duty factor range compared to PWM systems with a linear sawtooth oscillator. Stable operation at low duty factors is easily realized. For high efficiency, the frequency is reduced as soon as the duty factor drops below a certain value. This is accomplished by increasing the oscillator charge time. To ensure that the capacitor can be charged within the charge time, the value of the oscillator capacitor should be limited to approximately 1 nF. 8.3 Duty factor control The duty factor is controlled by the internal regulation voltage and the oscillator signal on pin RC. The internal regulation voltage is equal to the external regulation voltage (−2.5 V) multiplied by the gain of the error amplifier (typical 20 dB or 10×). The minimum duty factor of the switched mode power supply is 0 %. The maximum duty factor is set to 75 % (typical value at 100 kHz oscillation frequency). 8.4 Valley switching A new cycle is started at the primary stroke when the switch is switched on (see Figure 5). After a certain time (determined by the RC oscillator voltage and the internal regulation level), the switch is turned off and the secondary stroke starts. The internal regulation level is determined by the voltage on pin REG. After the secondary stroke, the drain 1 voltage shows an oscillation with a frequency of approximately ----------------------------- , where: 2π × L p C p Lp is the primary self inductance on the drain node. Cp is the parasitic capacitance on the drain node. As soon as the oscillator voltage is high again and the secondary stroke has ended, the circuit waits for a low drain voltage before starting a new primary stroke. The primary stroke starts some time before the actual valley at low ringing frequencies, and some time after the actual valley at high ringing frequencies. Figure 6 shows a typical curve for a reflected voltage N × Vo of 80 V. This voltage is the output voltage Vo (see Figure 7) transferred to the primary side of the transformer with the factor N (determined by the turns ratio of the transformer). Figure 6 shows that the system switches exactly at minimum drain voltage for ringing frequencies of 480 kHz, thus reducing the switch-on losses to a minimum. At 200 kHz, the next primary stroke is started at 33 ° before the valley. The switch-on losses are still reduced significantly.

Typical phase of drain ringing at switch-on 8.5 Demagnetization The system operates in discontinuous conduction mode all the time. As long as the secondary stroke has not ended, the oscillator will not start a new primary stroke. During the suppression time tsuppr, demagnetization recognition is suppressed. This suppression may be necessary in applications where the transformer has a large leakage inductance and at low output voltages.

All rights reserved. 7 of 20 TEA1623P; TEA1623PH NXP Semiconductors STARplug switched mode power supply controller IC 8.6 Protection 8.6.1 Overcurrent protection The cycle-by-cycle peak drain current limit circuit uses the external source resistor RI (see Figure 7) to measure the current. The circuit is activated after the leading edge blanking time tleb. The protection circuit limits the source voltage to Vsource(max), and thus limits the primary peak current. 8.6.2 Short-winding protection The short-winding protection circuit is also activated after the leading edge blanking time. If the source voltage exceeds the short-winding protection voltage Vswp, the TEA1623 stops switching. Only a power-on reset will restart normal operation. The short-winding protection also protects in case of a secondary diode short circuit. 8.6.3 OverTemperature Protection (OTP) An accurate temperature protection is provided in the TEA1623. When the junction temperature exceeds the thermal shut-down temperature, the IC stops switching. During thermal protection, the IC current is lowered to the start-up current. The IC continues normal operation as soon as the overtemperature situation has disappeared. 8.6.4 OverVoltage Protection (OVP) Overvoltage protection can be achieved in the application by pulling pin REG above its normal operation level, or by keeping the level of pin AUX above Vdemag. The current primary stroke is terminated immediately and no new primary stroke is started until the voltage on pin REG drops to its normal operation level. Pin REG has an internal clamp. The current feed into pin REG must be limited. 8.7 Characteristics of the complete power-plug 8.7.1 Input The input voltage range comprises the universal AC mains from 80 V to 276 V. 8.7.2 Accuracy The accuracy of the complete converter, functioning as a voltage source with primary sensing, is approximately 8 % (mainly dependent on the transformer coupling). The accuracy with secondary sensing is defined by the accuracy of the external components. For safety requirements in case of optocoupler feedback loss, the primary sensing remains active when an overvoltage circuit is connected. 8.7.3 Efficiency An efficiency of 75 % at maximum output power can be achieved for a complete converter designed for universal mains. 8.7.4 Ripple A minimum ripple is obtained in a system designed for a maximum duty factor of 50 % under normal operating conditions and a minimized dead time. The magnitude of the ripple in the output voltage is determined by the frequency and duty factor of the converter, the output current level, and the value and ESR of the output capacitor.

Soldering of through-hole mount packages 14.1 Introduction to soldering through-hole mount packages This text gives a very brief insight into wave, dip and manual soldering. Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. 14.2 Soldering by dipping or by solder wave Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 14.3 Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 °C and 400 °C, contact may be up to 5 seconds. 14.4 Package related soldering information Table 7.
