The first stage is a preregulator that translates the high rectified mains voltage to a low voltage and charges an external electrolytic capacitor. The second stage is a simple 5V regulator. The typical operating waveforms are shown in Figure 5. The device may be driven by a half wave or by a full wave using a bridge rectifier. Current flowing through the regulator stage is provided by a bipolar trilinton. It conducts for a limited time (0-t1; t2-T/2), set by external divider (R1-R2). The values of R1 and R2 have to be chosen in order to achieve the internal threshold value at the decided Vmains voltage. When the threshold pin voltage goes over V ref1, the series trilinton is switched off and remains in this state until voltage at the threshold pin again drops below the internal threshold. Using this technique, energy is drawn from the AC mains only during the low voltage portions of each positive half cycle, thus reducing the dissipation in the first stage. During the conduction angle, current provided by the trilinton is used to supply the loads and to charge the capacitor C1. In such a way, when the trilinton switches off, the loads receive the required currents by the capacitor discharge. For this reason it is important to properly set the conduction angle: during this period C1 has to reach a sufficient charge to guarantee that, at the end of discharging, the voltage drop between the capacitor and the OUTPUT1 pin is over 2.5V. Assuming that conduction angle has been set, two different possibilities can occur: 1) C1 value is such to reach Vcap(max) within the conduction angle. As the comparator also senses C1 voltage, when Vcap goes over Vcap(max), the trilinton would switch off. But doing so, the capacitor would discharge through the load so reducing its voltage. As soon as Vcap drops below Vcap(max), the trilinton switches on. As a consequence the trilinton reaches a stable condition limiting the current to a value sufficient to supply the loads and hold the capacitor voltage just below Vcap(max) (see figures 5b and 5c). 2) C1 value is such to reach Vcap(max) outside the conduction angle. In this case the trilinton doesn't reduce the current, but holds it to a constant value (ICL(in)) during the whole conduction angle (see figures 6a and 6b). Thus for each period the capacitor is charged twice. The ripple on the capacitor (OUTPUT2) depends on the following causes: - value of the capacitor - value of the total current supplied Thus it is possible to reduce it choosing the proper capacitor value according to the formula: Q t C = ------- = I tot ------V V with t T/2 The device has integrated current limit and thermal shutdown protections. The thermal shutdown turns the low voltage stage off (OUTPUT1=0V) if the die temperature exceeds a predetermined value. Hysteresis in the thermal sense circuit holds the device off until the die temperature cools down. Be careful that the thermal protection doesn't act on the OUTPUT2. CONDUCTION ANGLE CHOICE The power stage is a bipolar one; so in order to not exceed its SOA limits the ratio R1/R2 must be 11. Further choosing R1 and R2 in such a way that the capacitor is charged to its maximum voltage value (Vcap(max)) at the end of the conduction period, the power dissipated will be minimized. 5/14 1 VB409 / VB409SP / VB409(022Y) APPLICATION EXAMPLE FOR THE POWER DISSIPATION OPTIMIZATION In case of IOUT2=constant the average power dissipated on the device (Pdevice) can be calculated as follow: Pdevice= PIN - (IOUT2 . VOUT2 ) - (IOUT1 . VOUT1) (1) where PIN= average input power and VOUT2= average OUTPUT2 voltage Assuming that Itot= IOUT1 + IOUT2 (2) it is possible to use the below table data to evaluate through the formula (1) the minimum average power dissipation on the device.

Using formula (1) the minimum average power dissipation is: Pdevice = 0.8 - (10 * 13.7) * 10-3 - (15 * 5) * 10-3 0.6W Figure 4: Application scheme MAIN INPUT Cap (OUTPUT2) C1 Input current limiter VZ Threshold + R1 ILOAD2 Vref1 Thermal protection Vref2 R2 Output current limiter OUTPUT1 Vref3 RLOAD VB049a1 6/14 1 VB409 / VB409SP / VB409(022Y) Figure 5: typical waveforms Rectified Main Vmax V1 Figure 5a t1 t2 T/2 T t Figure 5b Vcap (OUTPUT2) Vcap(max) Vcap(min) t Figure 5c IIN ICL(in) t VOUT1 Figure 5d t 7/14 1 VB409 / VB409SP / VB409(022Y) As before explained, the device also senses the preregulator voltage (Vcap), so that as soon as the capacitor reaches its maximum voltage, the trilinton reduces the current so limiting furtherly power dissipation. On the contrary if the capacitor doesn't reach the maximum value, the trilinton supplies current at a steady value (Imax) during the whole conduction angle: VIN vmax V1 Figure 6a 0 IIN ICL(in) t1 t2 T/2 T t Figure 6b t Vcap Figure 6c t 8/14 1 VB409 / VB409SP / VB409(022Y) PENTAWATT HV MECHANICAL DATA DIM.
