    A Variable Switching Power Supply using LM2576 [Buck Converter, CC-CV]

    Hi,

    Please mention your opinion regarding the circuit and PCB, Thanks.

    Abstract

    Switching power supplies are known for high efficiency. An adjustable voltage/current supply is an interesting tool, which can be used in many applications such as a Lithium-ion/Lead-acid/NiCD-NiMH battery charger or a standalone power supply. In this article, we will learn to build a variable step-down buck converter using the popular LM2576-Adj chip.
