ST AN966 Application Note
This document introduces the L6561 power converter application. The power converter uses the TM technique to achieve power factor correction, which has high power factor and low harmonics.
ST TSM101 Application Note
The TSM101 is a voltage and current controller providing a more integrated solution in Switching Mode Power Supply application versus common standard ICs solution, with more functions widely used in power control in a single IC. This application note shows three basic configurations of the IC, to be used in the secondary side of any SMPS. Functions described are precise secondary voltage regulation, current limiting with foldback function, window detector with output feedback to opto-coupler or power good signal to CPU.

ST AN487 Application note handbook
This document introduces the development of high-efficiency circuits using switched mode techniques, which offer space saving and cost reduction, particularly in the heatsink and output LC filter. A new technology called MULTIPOWER-BCD has been developed for these applications, allowing the integration of isolated power DMOS elements, bipolar transistors, and CMOS logic on the same chip. This technology is especially suitable for switch mode applications due to its high efficiency, fast switching speed, and no secondary breakdown of the power DMOS element. With MULTIPOWER-BCD, the L497X family has been implemented, which is a new series of fully integrated switching regulators suitable for DC-DC converters operating in Buck configuration. The family consists of five devices with different output current values (2A, 3.5A, 5A, 7A, 10A). The devices rated at 2A and 3.5A are assembled in Power Dip (16+2+2) package, while the others are assembled in the Multiwatt15 package. Each device integrates a DMOS output power stage, a control section, limiting current, and supervisor functions such as reset and power fail signal for microprocessor applications. The output voltage can be adjusted starting from the internal reference voltage.
