USER GUIDE | UG:304 PI354X-00 Evaluation Board User Guide 36 V to 60 VIN, 2.5, 3.3, 5.0, and 12 VOUT Cool-Power ® Buck Regulator & LED Driver ContentsPage Introduction Evaluation Board Supply & Load Connections 2 Bill of Materials PI3546-00-EVAL1 PI3545-00-EVAL1 PI3543-00-EVAL1 PI3542-00-EVAL1 The PI354X-00 evaluation board demonstrates the features and benefits of Picor’s ZVS high-voltage Buck Regulator family. There are four preconfigured evaluation boards available: PI3542-00-EVAL1 (2.5 V), PI3543-00-EVAL1 (3.3 V), PI3545-00-EVAL1 (5.0 V) and PI3546-00-EVAL1 (12.0 V). Please refer to the PI354X-00 data sheet for individual regulator’s specifications and design instructions. 3 4 5 6 The evaluation board provides several options for applying input power (VIN and GND) and output load (VOUT and GND). The user can solder tab style banana jacks or wire, use threaded connectors with retaining nuts, or solder turret pins for clip-on connections. Schematics7 Mechanicals8 Picor PCB Edge Connector Description PCB Gerber Files 9 11 The evaluation board family can demonstrate all the PI354X-00’s features accessible to the user. The general purpose amplifier (VDIFF) is preset with a gain of two, but can be easily re-configured for differential measurements by adding extra 0603 resistors (RD1-RD5). The lighting option (LGH) can be explored by ordering any of the evaluation boards. When using the lighting option, connections are made between the VIN (anode) and the LGH (cathode) terminals (see Figure 3). Three parallel shunt footprints (2512) are available to program a desired LED constant current. Each evaluation board is preset with a constant current of 1.0 A implementing three 0.3 Ω resistors in parallel (RS1-RS3). R6, R7, and C22 are used to set the LGH compensation (please refer to the data sheet for design calculations, theory of operation, as well as maximum compliant voltage requirements). REA1 and REA2 are used to adjust the output voltage regulation. There are additional schematic features that allow a low frequency dimming circuit (included on the PI3543-00-EVAL1-00 only) to be utilized. This consists of a MOSFET and driver circuit to allow the user to pulse the LED on and off using an external dimming PWM signal. This signal should be limited to less than 10 kHz. Since dimming circuity is only available on the PI3543-00-EVAL1, be sure to order that part number if LED dimming is to be explored. Figure 1. Representative sample (board layout and size will vary) UG:304 vicorpower.com Applications Engineering: 800 927.9474 Page 1 The I/O pins are brought out to the right edge of the evaluation board to allow for easy monitoring or for adding additional circuitry. The status of the Power Good pin is indicated by a dual colored LED; red indicates that the regulator is disabled (EN = 0V) or faulting and green indicates that the regulator is enabled (EN > 1.1 or floating) and operating correctly. The SYNCO and SYNCI pins are accessible to allow for paralleling modules or for synchronization to an external clock. A footprint (CTRK) for an external capacitor (0603) is available to tailor the start-up profile of the converter. The error amplifier’s output (EAO) is brought to a pin and in conjunction with the TRK pin, can be used for paralleling two converters. The board was designed with an edge connector to facilitate in-house testing, but can be also used for evaluation purposes. The printed circuit board is four layers FR-4 170Tg material with 2oz copper layers, ENIG pad finish and a board thickness of 0.062. Evaluation Board Supply & Load Connections Figure 2.
