The flyback (the vertical portion of the sawtooth wave) can be a potential problem for the flyback transformer if the energy has nowhere to go: the faster a magnetic field collapses, the greater the induced voltage, which, if not controlled, can flash over the transformer terminals. The high frequency used permits the use of a much smaller ...
Fig. 1: Schematic of a flyback converter. The flyback converter is used in both AC/DC, and DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation.

Their reputation for reliability was however partially marred by higher failure rates on certain models, such as the 14/16/20P1 employing the DS19 flyback transformer prone to internal arcing, EEPROM corruption due to bugs in the ST92195B5B1/MOH microcontroller, or non-user-upgradeable early DVB-T modules incapable of handling over 255 channels ...
The Samsung Alias 2 was the successor of the original Samsung SCH-U740, which did not feature the unique "magic" e-ink display. The keys were cramped up with all the functions of the e-ink display, which disappointed many users. The phone was available in the United States in March 2007 and in Canada in August 2007.
The flyback transformer is also known as an IHVT (Integrated High Voltage Transformer) if it includes a voltage multiplier. The flyback uses a ceramic or powdered iron core to enable efficient operation at high frequencies. The flyback contains one primary and many secondary windings that provide several different voltages.
Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.
The Samsung SPH-N270 or Matrix phone is a bar style mobile phone released in 2003, made to resemble the phone used in The Matrix Reloaded. The design crew of the Matrix worked closely with Samsung to develop a phone whose features and release date would coincide with the movie. The SPH-N270 was not intended as a mainstream phone for everyday use.
