Embodiment Construction

[0016] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that the specific details need not be employed to practice the invention. In other instances, well-known materials or methods have not been described in detail in order not to obscure the invention.

[0017] Reference throughout this specification to "one embodiment," "an embodiment," "an example," or "an example" means that a particular feature, structure, or characteristic described with respect to the embodiment or example is included in the present specification In at least one embodiment of the invention. Thus, appearances of the phrases "in one embodiment," "in an embodiment," "an example," and "an example" in various places throughout this specification are not necessarily all referring to the same embodiment or implementation. example. Furthermore, the par...

Abstract

Methods and apparatuses for programming a parameter value in an IC (e.g., any power electronic device, such as a controller of a power converter) are disclosed. The parameter can be selected / programmed by selecting a clamp using an external optional (selectively inserted) diode (coupled to a multi-function programming terminal). In particular, a controller IC for a power converter can be externally programmed via one or more multiple function terminals during startup of the converter to select between two or more options using the external programming terminal(s). Once programming is complete, internal programming circuitry may be decoupled from the programming terminal and during normal operation the programming terminal may then be used for another function, such as a bypass (BP) terminal to provide a supply voltage to the IC or other required functionalities.

Description

technical field [0001] The present disclosure relates generally to integrated circuits (ICs) in power electronics, and particularly, but not exclusively, to programmed controllers for switch-mode power converters. Background technique [0002] Many power electronic IC devices allow a choice between two or more functional parameters of the device. Conventional programming methods program these IC devices using resistors or capacitors placed at dedicated terminals of the device. Therefore, to program an IC device, additional terminals may be added to the device for each additional function or programmable parameter, which translates into increased cost, power consumption and space requirements of the device. [0003] One example implementation of an IC with selectable parameters is a controller for a switch-mode power converter. For example, many household and industrial applications require regulated direct current (dc) power to operate. Since conventional wall outlets typ...
