PowerPSoC Intelligent LED Driver

CY8CLED04G01, CY8CLED03G01, CY8CLED03D01, CY8CLED03D02, Y8CLED04D01, CY8CLED04D02 The PowerPSoC family incorporates programmable system-on-chip technology with the best in class power electronics controllers and switching devices to create easy to use power-system-on-chip solutions for lighting applications. All PowerPSoC family devices are designed to replace traditional MCUs, system ICs, and the numerous discrete components that surround them. PowerPSoC devices feature high performance power electronics including 1A 2 MHz power FETs, hysteretic controllers, current sense amplifiers, and PrISM/PWM modulators to create a complete power electronics solution for LED power management. Configurable power, analog, digital, and interconnect circuitry enables a high level of integration in a host of industrial, commercial, and consumer LED lighting applications.

This architecture integrates programmable analog and digital blocks to enable the user to create customized peripheral configurations that match the requirements of each individual application. Additionally, the device includes a fast CPU, Flash program memory, SRAM data memory, and configurable I/O in a range of convenient pinouts and packages.

The PowerPSoC architecture, as illustrated in the block diagrams, comprises five main areas: PSoC core, digital system, analog system, system resources, and power peripherals which include power FETs, hysteretic controllers, current sense amplifiers, and PrISM/PWM modulators. Configurable global busing combines all the device resources into a complete custom system. The PowerPSoC family of devices have 10-port I/Os that connect to the global digital and analog interconnects, providing access to eight digital blocks and six analog blocks.

The CY8CLED04D0X is the first product in the PowerPSoC family to integrate power peripherals to add further integration for your power electronics applications.The PowerPSoC family of intelligent power controller ICs are used in lighting applications that need traditional MCUs and discrete power electronics support.The power peripherals of the CY8CLED04D0X include four 32V power MOSFETs with current ratings up to 1A each. It also integrates gate drivers that enable applications to drive external MOSFETs for higher current and voltage capabilities.

The controller is a programmable threshold hysteretic controller, with user-selectable feedback paths that uses the IC in current mode floating load buck, boost, and floating load buck/boost configurations.
