Temperature Detection Application of FMKS Series This section shows an example about a temperature detection circuit of a secondary rectifier diode in off-line flyback converters. Figure 6-1 shows the reference of temperature detection circuit with a NTC thermistor. The NTC thermistor, coupled thermally with DS secondary rectifier diode, is connected to the REF pin of the output voltage detection circuit in the converter. As shown in Figure 6-2, as the temperature rises, the resistance of the NTC thermistor decreases. When the temperature of DS rises due to such a cause as overload state, the resistance of NTC thermistor decreases, and the ratio of resistance voltage divider is changed. When the voltage of RS shown in Figure 6-1 reaches the reference voltage of U1 shunt regulator, the current flows to PC1 optocoupler, and the converter IC in the primary limits the output power. Thus, the rise of DS temperature can be limited. DS T1 OUT (+) NTC PC1 ● Increasing the accuracy of temperature detection by reducing the thermal resistance between D S and the thermistor, it is necessary to attach the thermistor to DS with high thermal conuctivity material between them. In contrast with the temperature detection of thermistor, the FMKS series can achieve high accuracy of temperature detection by the following. ● The internal structure is formed a Schottky barrier diode for temperature detection, SBD, and a fast recovery diode, FRD, on the same die as shown in Figure 6-3. Thus, the temperature is about the same between SBD and FRD. ● The temperature detection uses the temperature characteristics of the leakage current for SBD, which increases as the temperature rises as shown in Figure 6-4. The temperature detection circuit with FMKS series has the following advantages. ● Highly accurate and stable temperature detection of FRD. ● Real time temperature detection of FRD. ● Circuit component reduction such as thermistor, and easy attachment. ● Power supply downsizing.

In the case that FMKS series and the synchronous rectification device, QSYN, for the other output are attached on the same heatsink so that the temperature from QSYN is conducted to FMKS series, the FMKS series can detect the temperature in the following. ANODE 1 of SBD PC1 Converter IC FB REF U1 PC1 5 Reverse Leakage Current, IR (mA) Figure 6-5 shows the reference of temperature detection circuit with FMKS series. The ANODE pin of SBD for the temperature detection in DS secondary rectifier diode is connected to the REF pin of the shunt regulator of the output voltage detection circuit in the converter. When the temperature of DS rises due to such a cause as overload state, the leakage current, IR, of SBD for temperature detection increases, and the voltage of RS shown in Figure 6-5 increases. When RS voltage reaches the reference voltage of U1 shunt regulator, the current flows to PC1 optocoupler, and the converter IC in the primary limits the output power. Thus, the rise of DS temperature can be limited. U2 RS (-) Figure 6-5 Reference temperature detection circuit with FMKS series. ● The overload state of QSYN. ● The rectification state by the rectifier diode in QSYN because the synchronous rectification IC malfunctions and thus QSYN is kept off. Synchronous rectification IC In Figure 6-5, RS value is calculated as follows. Mount on same heatsink. OUT1 (+) T1 QSYN DS 3 where, VREF is the reference voltage of U1 shunt regulator, IR(TD)MAX is the maximum leakage current of SBD at the temperature detection value of TD in Figure 6-6 or Section 3.1. When TD is 115 °C, IR(TD)MAX is 1 mA as shown Figure 6-6. Thus, when VREF is 2.5 V, RS value is 2.5 kΩ, and thus the FMKS series can detect in the range of 115 °C to 127 °C. When RS value is chosen 2.7 kΩ from E24 series close to the above value, IR(TD)MAX is 0.93 mA, and thus the temperature detection range is 114 °C to 126 °C. OUT2 (+) 2 FMKS PC1 Converter IC ANODE 1 of SBD FB REF PC1 RS U1 U2 (-) Figure 6-7 Reference circuit with FMKS series in the multi-output flyback converter circuit When the junction temperature of SBD rises close to 150 °C, the leakage current of SBD increases rapidly and the power dissipation increases. Thus, RS should be set so that the temperature is detected in 140 °C or less including variation. FMKS-DSE Rev.1.0 SANKEN ELECTRIC CO.,LTD.
