Design an AC-DC flyback power supply using an STCH03 controller webinar
 | Learn about the new ultra-low standby controller for flyback switched mode power supplies |
Intended for relative newcomers to the field of power supplies who want an overview of a flyback converter's behavior and its modes of operation, this webinar will show how to design a flyback switched mode power supply using our new STCH03 quasi-resonant PWM controller.
With improved power density, low stand-by power and reliability, even more advance designers will benefit from the integrated features of our new PWM controller; making the design and operation easier, more effective and reliable.
Agenda
- Overview of how flyback converters operate
- Features of the STCH03 quasi-resonant PWM controller
- Selecting the best MOSFETs for high-voltage switches
- Advantages of secondary-side rectification (or Efficient designs for secondary-side rectification)
- Using a clamper circuit to place the positive or negative peak in converter applications

Product details
STCH03 - A compact quasi-resonant PWM controller specifically designed for ultra-low standby power supplies below 10mW. It combines a high-performance low-voltage PWM controller chip and a 650V HV start-up cell in the same package. The device features a unique characteristic: it is capable of providing constant output current (CC) regulation using primary-sensing feedback.
800-1700 V MDmeshTM K5 - Very high voltage super-junction Power MOSFET series. Extremely good RDS(on) at very high BVdss and high switching speed gives high efficiency with lower design complexity for mainly flyback topologies
FERD - Lower VF x IR than corresponding Schottky diode, smaller chip than Schottky for the same current rating and lower thermal coefficient these new 45V, 60V & 100V structured field-effect rectifier diodes enhance application performance and compactness.
