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 1 ampere 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 you to create customized peripheral configurations that match the requirements of each individual application. Additionally, the device includes a 24 MHz 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, consists of 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 of 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.PowerPSoC is designed to operate at voltages from 7 V to 32 V, drive up to 1 ampere of current using internal MOSFET switches, and over 1 ampere with external MOSFETs.
This family of devices (CY8CLED0xD/G0y) combines up to four independent channels of constant current drivers. These drivers feature hysteretic controllers with the rogrammable System-on-Chip (PSoC) that contains an 8-bit microcontroller, configurable digital and analog peripherals, and embedded flash memory.
The CY8CLED0xD/G0y 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 CY8CLED0xD/G0y include up to four 32 volt power MOSFETs with current ratings up to 1 ampere 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, floating load buck-boost, and boost configurations.
