This voltage converter is built with TL497A and converts an input voltage of 5…12 voltage to a higher level of 15…30 volts. This is specially helpfull in mobile applications where power supply levels are commonly limited to 12 volts supplied by batteries.

The voltage converter circuit uses the TL497A as a flyback-voltage converter. The choke coil [...]

This is a simple low-cost 12 Volt 50W off-line switching power supply, which can be used for home projects or to learn operation of flyback converters. It can work over a universal AC line input range 90-264 VAC and provides a 12VDC output at more then 4A load. Line and load regulation is better then [...]

All high-current switchers are sensitive to board layout; take care when designing the pc board. You’ll obtain the best results by using a multilayer board, so you can dedicate a single layer to ground plane. You should tie the “power” components (C1, C2, C16, D2, C12, C13, C14) directly to this ground plane and group [...]
