Important Note: Although this board is designed to satisfy safety isolation requirements, the engineering prototype has not been agency approved. Therefore, all testing should be performed using an isolation transformer to provide the AC input to the prototype board. Design Reports contain a power supply design specification, schematic, bill of materials, and transformer documentation. Performance data and typical operation characteristics are included. Typically only a single prototype has been built.

5 Circuit Description
This circuit is configured as a Flyback operating in both continuous and discontinuous conduction mode. The low standby consumption is achieved by using a high gain optocoupler, using a bias winding that provides about 10V during no-load, and by designing a low-capacitance transformer. 5.1 Input Rectification, Bulk Capacitance and EMI Filtering AC input power is rectified by a full bridge, consisting of D1 through D4. The rectified DC is then filtered by the bulk storage capacitors C1 and C2. Inductor L1 and Ferrite bead L2 separate C1 and C2 from each other. L1, C1 and C2 form a pi () filter, which attenuates conducted differential-mode EMI noise. Fusible resistor RF1 has multiple functions. It is a fuse, an in-rush current limiting device, a final low pass filter stage (with C1) for conducted EMI attenuation and an initial stage of input surge voltage attenuation. 5.2 Primary DRAIN Voltage Clamp Circuit The DRAIN voltage clamp circuit is comprised of C3, R1, R2 and diode D5. D5 and C3 clamp the amplitude of the voltage spike that the transformer leakage inductance generates, at switch turn-off, to keep it beneath the device's maximum DRAIN to SOURCE voltage rating (700 V). R2 damps the high frequency ringing caused by leakage inductance, which improves the conducted EMI performance of the circuit. 5.3 Auxiliary Bias Supply The TinySwitch-II normally does not need a bias supply because it has a high voltage current source to supply the internal chip consumption. If an external current is applied to the BP pin (which is the internal power supply of the chip), it turns off the HV current source and regulates the voltage on the BP pin like a zener. The power dissipated in the HV current source is saved. This power savings is on the order of 50-100 mW. This is needed to achieve a <100mW standby consumption. The auxiliary bias supply circuit is made up of the primary-side transformer bias winding, diode D6 and capacitor C5. D6 rectifies the output of the winding and C5 filters it. The winding was given just enough turns so that its minimum output voltage stays at 10V at no-load to minimize power consumption. C4 is the standard BP pin decoupling capacitor, which should always be a 50 V 0.1F ceramic capacitor that is located close to the IC. R3 is used to regulate the current into the BP pin. 5.4 Output Rectification and Filtering Output rectification and filtering are accomplished by Schottky diode D7, capacitors C6 and C7. D7 rectifies the output of the transformer, T1. R10 and C8 dampen out the high frequency interaction between D7, T1 and U1, to reduce conducted EMI noise generation. C6 filters the initial rectified output, while L3 and C7 serve as a secondary low-pass filter stage, which further reduce the output ripple voltage.

5.5 Output Voltage Sensing and Feedback Transistor Q1, resistors R4, R5, R6, R7, R8, R9, diode D8, Zener diode VR2 and optoisolator U2 form the CV, CC, and cable drop compensation circuit. Q1, R6, R7, R8, R9, VR2, D8 and U2 comprise the Constant Voltage (CV) mode control loop and cable compensation control loop while R4, R5 and U2 make up the Constant Current (CC) mode control loop. CC Mode Operation The CC mode set-point is determined by the voltage drop on the optocoupler LED and the voltage drop on R5. The voltage drop on R4 is quite small and can be ignored. The TinySwitch-II has an EN pin current that is very constant with power delivery, so therefore the current in the optocoupler LED is very constant. For this reason the CC set-point does not change with load voltage. CV Mode and Cable Drop Compensation Operation The CV mode set-point is set by the voltage drops on VR1, R7, and the Vbe of Q1. The voltage on R7 depends on the operation of the cable drop compensation circuit. In order to have a regulated voltage at the end of the cable, the load current produces a voltage drop on R9 which feeds to the Base of Q1, through R8. The net effect is that the voltage set-point increases as the load increases, canceling the voltage drop in the output cable. D6 provides temperature compensation for the temperature coefficient of Q1.

12.4 Output Ripple Measurements 12.4.1 Ripple Measurement Technique For DC output ripple measurements, a modified oscilloscope test probe must be utilized in order to reduce spurious signals due to pickup. Details of the probe modification are provided in Figure 19 and Figure 20. The 5125BA probe adapter is affixed with two capacitors tied in parallel across the probe tip. The capacitors include one (1) 0.1 F/50 V ceramic type and one (1) 1.0 F/50 V aluminum electrolytic. The aluminum electrolytic type capacitor is polarized, so proper polarity across DC outputs must be maintained (see below).
