USER GUIDE | UG:302 PI33xx-xx-EVAL1 & PI34xx-xx-EVAL1 ZVS Regulators Buck Evaluation Board Contents Page Introduction 1 Evaluation Board Supply & Load Connections 4 Bills of Materials 7 Evaluation Board Notes 13 Introduction The PI33xx-xx-EVAL1 and PI34xx-xx-EVAL1 evaluation board demonstrates the features and benefits of the ZVS Buck Regulator PI33xx and PI34xx families. The board features the ZVS Buck Regulator SiP, along with inductor, ceramic input and output capacitors. The evaluation board provides several options for making input power (VIN and GND) and output load (VOUT and GND) connections. The user can solder tab style banana jacks or wire, use threaded binding posts secured by a retaining nut, or to simply use a #6 nut and bolt connection. All the I/O pins are labeled and routed to the board edge for easy access. Each I/O pin is accompanied with an adjacent 50mil through-hole for adding a test point or to facilitate wiring to external circuitry. The board has a scope tip jack for measuring output voltage (VOUT ), and has locations for two optional jacks for measuring VIN and the switching node of the regulator (See Figure 4). There are two headers installed: an ENABLE jumper which can be used to enable or disable the converter and the remote sense jumper that will connect the buck’s remote sense pin to the output at the VOUT terminal. Connections required for parallel regulator operation are grouped together (labeled Current Sharing) to allow for easy connection between evaluation boards. There is a zero ohm jumper between SYNCI and SGND to ensure that SYNCI is grounded when not used. This resistor must be removed for interleaved operation. Please refer to the product data sheet for more detailed information on paralleling and on interleaving units. There are two unpopulated resistor footprints (RADJ1 and RADJ2) used in trimming the output voltage and a capacitor footprint (CTRK) to add additional capacitance to the output tracking pin. Please refer to the product datasheet for more detailed information on these topics. The evaluation board is constructed using 4 layers of 2oz copper and is routed to optimize the regulation path between input and output voltage, which reduces the parasitic losses and yields the best efficiency.

There are two additional, unmarked, scope tip test points (circled in red in Figures 8 – 10) that allow the user to measure VIN and the switching node (VS1). These are labeled as JJVIN and JJVSW in Figures 8 – 10. There are two through-hole pads (blue circle) for the addition of an electrolytic bulk storage capacitor. This capacitor is required when the evaluation board is connected to the input voltage source through long leads. A 100µF, 50V Electrolytic is recommended with an ESR between 20 and 50mΩ. The two pins labeled as “N/C” (highlighted in green box in Figures 8 – 10) are not electrically connected to each other. There are internal connections within the PI33xx and PI34xx between grounds SGND and PGND. It is not required to tie these two grounds together externally and these two grounds are not connected together on the evaluation board.
