Page 14: Install Hardware
Getting Started Install Hardware 2.5.1 Board Wiring Instructions The CY3267 PowerPSoC EVK main board has five screw-terminal blocks to connect the LED daughter board. The four-post terminal block (J15) is used as the I C interface between PowerPSoC and the thermistor on the LED board. This terminal block contains the following signals: Table 2-1. - Page 15 Getting Started Figure 2-6. CY3267 Power EVK Main Board Wiring Scheme The positive terminal of each LED connector is a common terminal for LED connections in buck topology, boost topology, and buck-boost topology.

Page 17: Kit Operation
Kit Operation Introduction The CY3267 PowerPSoC Lighting EVK ships with factory-installed firmware that demonstrates the ability of PowerPSoC to drive multiple LED channels with color-mixing intelligence. The firmware also illustrates the use of PSoC Designer to design PowerPSoC-based systems and solutions. The factory-installed code example implements the following elements with PowerPSoC: C interface to receive the desired color coordinates and intensity information ■... -
Page 18: Programming The Powerpsoc Device
Kit Operation The CY8C24894 device takes the input from the GUI over the USB interface and passes it on to the PowerPSoC over the I C interface. The PowerPSoC firmware receives the target color coordinates and calculates the intensities of each of the four individual colors (red, green, blue, and amber) using an intelligent color-mixing algorithm. - Page 19 Kit Operation 5. In the Program Part dialog box, verify that the Port Selection field shows the connection to a MiniProg1. Figure 3-2. Program Part Dialog 6. If the board is not powered yet, set the Acquire Mode radio button to Power Cycle. If the board is powered, set the Acquire Mode to Reset.

Hardware 4.1.2 PowerPSoC The CY3267 Power EVK main board is populated with components for the floating-load buck topol- ogy. The floating load buck topology (see Figure 4-8 as an example) consists of two ceramic input bypass capacitors (0.1 µF and 1.0 µF) each rated for 50-V in 0603 package size. These are low equivalent series resistance (ESR) type capacitors. - Page 26 Hardware Figure 4-7.

Page 37: Representing Colors
Software Representing Colors The application has two modes of control: CIE Color Selection Mode and Direct LED Control Mode; Figure 5-1. These two modes are selected using tabs displayed on the upper-left edge of the application window. The CIE Color Selection Mode is the active display when the application is started and is intended to be the most common mode used to control the CY3267 PowerPSoC Light- ing EVK. - Page 38 Software Figure 5-3. Intelligent Lighting Control – Direct LED Control The application can also limit color choices to those that are produced by a black body radiator. A black body radiator is a theoretical, color-neutral object defined by Planck’s Law. A black body radia- tor glows (radiates energy) at different colors as it is heated.
- Page 39 Software Figure 5-4. CIE Color Selection Tab - Color Temperature Control In addition to displaying colors, the application allows you to directly control the LEDs. The state of the LEDs (ON or OFF) is based on a closed loop between the application and the CY3267 Power EVK main board that determines the actual ON/OFF state.
-
Page 40: Led Luminous Flux
Software LED Luminous Flux The luminous flux of the mixed color output can be varied using the Requested Luminous Flux slider located on the right side of the application window. The maximum total flux produced by the LEDs varies, depending upon the chosen color. For example, a neutral white can be set to a higher total flux than any of the four primary colors alone, because the color white is represented by a sum of the light output of each of the LEDs. -

It provides cycle-by-cycle switch control with a fast transient response. The hysteretic controller simplifies system design because it does not require external compensation. The gate drivers are used to drive either internal or external power FETs.
