Benefits of technology

The invention provides a way to change the operation of a power conversion system without needing many additional pins on the control circuit. This is achieved by using a current sensor to detect the current flow through a specific pin and adjusting the control settings to ensure the pin performs its functions correctly. This results in a more efficient and effective use of pins, reducing the number of pins needed on the control circuit.

Problems solved by technology

However, since the increase in the number of pins leads to an increase in packaging cost, in consideration of the cost, an increase in the number of signal pins is generally to be avoided if possible.
Therefore, how to decrease the number of pins of the control circuit while maintaining normal operation of the control circuit is one critical issue in designing an integrated circuit.

Embodiment Construction

[0019]FIG. 1 is a schematic view of a power conversion apparatus according to an embodiment of the invention. Please refer to FIG. 1. A power conversion apparatus 100 includes a power conversion circuit 102 and a control circuit 104. The power conversion circuit 102 is coupled to the control circuit 104, wherein the power conversion circuit 102 includes an upper bridge switch SW1 and a lower bridge switch SW2. The upper bridge switch SW1 and the lower bridge switch SW2 are connected in series between an input voltage Vin and a ground. A common contact point N1 of the upper bridge switch SW1 and the lower bridge switch SW2 is coupled to the control circuit 104. The control circuit 104 includes a detecting circuit 106 and an adjusting signal generating circuit 108. The detecting circuit 106 is coupled to a boot voltage input pin PBT1 and the adjusting signal generating circuit 108 of the control circuit 104. The adjusting signal generating circuit 108 is further coupled to the common ...

Abstract

A power conversion apparatus is provided. A detecting circuit detects a current flowing into a boot voltage input pin and converts the current into a corresponding detecting voltage. An adjusting signal generating circuit generates an adjusting signal according to the detecting voltage. A control circuit adjusts control parameters thereof according to the adjusting signal.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefits of Taiwan application serial no. 105136571, filed on Nov. 10, 2016. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTIONField of the Invention[0002]The invention relates to an electronic apparatus, and more particularly, to a power conversion apparatus.Description of Related Art[0003]When functions of an integrated circuit are increased, the number of pins needs to be increased in order to receive input signals and / or output signals corresponding to the new functions. However, since the increase in the number of pins leads to an increase in packaging cost, in consideration of the cost, an increase in the number of signal pins is generally to be avoided if possible. For example, in a control circuit configured to control light emission of a light emitting diode, the number of pins is pr...
