AN52209 - CY8CLED0xx0x PowerPSoC® - Hardware Design Guidelines

Last Updated: 
Jun 26, 2020

The Cypress PSoC® family of devices is well established in the field of programmable mixed-signal microcontroller-based devices. The traditional method of implementing power management systems (for example, high-brightness LED lighting systems) involves using a similar system-on-chip to interface with high-power discrete devices, such as constant current drivers and MOSFET switches.

In PowerPSoC®, the classic PSoC core is combined with high-performance power electronics. This results in an integrated intelligent power electronics solution in a single QFN package. The intent of PowerPSoC is to significantly reduce the BOM cost, part count, and board space for implementing power management systems while retaining performance. CY8CLED04D01 family of devices combines up to four independent channels of constant current drivers.

The level of integration and versatility offered by PowerPSoC can lead to considerable simplification of design, thus allowing the designers who are less familiar with power electronics domain to venture into these designs. In order to avoid oversimplification and/or overlooking of certain fundamental system-level considerations, Cypress offers this document to address the following four key issues in any power conversion system design: thermal, layout, transient handling, and ESD. By gaining familiarity with the issues and employing suggested techniques and guidelines in these chapters, the designers will certainly improve the integrity of their designs and likelihood of first pass success.

Dear valued customer,
