1. Two-switch topology benefits forward and flyback power converters
   Robert Bell
   Supply ON Semiconductor MTP20N20E MTP33N10E
   Designers tend to favor forward- and flyback- converter topologies for loads less than 200 W because they are simple and can power multiple isolated outputs. Their simplicity is partially based on the fact that these converters use a single ...

2. Use copper to temperature-compensate high current measurements
   Jerry Steele
   Measurement ON Semiconductor NCS333
   Large currents flowing in a length cable can be measured using the voltage drop along the cable. It eliminates the need for a bulky shunt or expensive magnetic measurement method. Accuracy is limited however because of the +0.39%/ C tempco ...

3. Circuit distorts duty cycle for CML inputs
   Dieter Verhulst Xin Yin
   Oscillators ON Semiconductor MC100EP16 NCP565-D
   To test a gigabit-speed data-recovery chip, you need a clock with a controllable duty cycle. Because most pattern and clock generators have a fixed duty-cycle output of 50%, the design may require a small circuit to distort the duty cycle. The ...

4. The start-up transistor works once!
   Daniel Dufresne
   Supply ON Semiconductor MPSA42
   It’s the mid 1990’s and I am a design engineer for a company that designs and manufactures custom measurement systems and high power electronics. Our customers range from experimental fusion reactor operators to electric utilities. One ...

5. Circuit adds programmability to sensor amplifier
   Chuck Wojslaw
   Measurement Amplifiers ON Semiconductor CAT5113 CAT5114
   The pressure-sensor amplifier circuit of Figure 1 offers a number of advantages over the traditional approach using the classic three-op-amp instrumentation amplifier. The circuit can operate from a single supply and uses only two op amps and 1% ...

6. JFETs Offer LC Oscillators with Few Components
   Herminio Martinez
   Oscillators ON Semiconductor 2N3819
   By using JFETs in unusual configurations, you can design simple, high-frequency LC oscillators with few passive components. The structure for implementing the amplifier stage comprises a JFET transistor that you configure as a common drain (Figure ...

7. Circuit reduces negative-voltage stresses on control IC
   Supply ON Semiconductor MBRD835L
   In a synchronous, buck switching power supply, the two FETs and the output inductor meet at the phase node (Figure 1). The phase node often connects directly to the control IC. The voltage on this node swings from the input voltage to some voltage ...
