Cool-Power® 28 Volt M Grade 28 VIN, 3.3 V to 15 VOUT, Cool-Power ZVS Isolated DC-DC Converter Modules Product Description Features The Cool-Power ZVS Isolated Converter Module Series consists of high density isolated DC-DC converters implementing Zero Voltage Switching topology. • Efficiency up to 88% The 28Vin Cool-Power series operates over a wide range input of 16 V to 50 Vdc, delivering 50 W of output power, yielding an unprecedented power density of 334 W/in3. • Proprietary “Double-Clamped” ZVS Buck-Boost Topology These converter modules are surface mountable and only ~.5" square in area achieving ~50% space reduction versus conventional solutions. • Very low profile (0.265 in) • High switching frequency minimizes input filter requirements and reduces output capacitance • Proprietary isolated magnetic feedback • Small footprint (0.57 in2) enables PCB area savings • Wide input voltage range operation (16-50 Vdc) • On/Off Control, positive logic • Wide trim range +10/-20% most models Output Voltage Device Set IOUT Max Range PI3108-00-HVMZ 3.3 V 2.97 to 3.63 V 10 A PI3109-00-HVMZ 5V 4 to 5.5 V 10 A PI3106-00-HVMZ 12 V 9.6 to 13.2 V 4.2 A PI3111-00-HVMZ 15 V 12 to 16.5 V 3.33 A The switching frequency of 900 kHz allows for small input and output filter components which further reduces the total size and cost of the overall system solution. The output voltage is sensed and fed back to the internal controller using a high performance isolated magnetic feedback scheme which allows for high bandwidth and good common mode noise immunity. The PI31xx-00-HVMZ series requires no external feedback compensation and offers a total solution with a minimum number of external components. A rich feature set is offered, including output voltage trim capability, output over-voltage protection, adjustable soft-start, over-current protection with auto-restart, over and under input voltage lockout and a temperature monitoring and protection function that provides an analog voltage proportional to the die temperature as well as shut down and alarm capabilities. • Temperature Monitor (TM) & Over-Temperature Protection (OTP) • Input UVLO & OVLO and output OVP • Over current protection with auto restart • Adjustable soft-start • 2250 Vdc input to output isolation • Surface Mountable 0.87” x 0.65” x 0.265” Applications • Wide Temperature, Aerospace & Defense Applications • Space Constrained Systems • Isolated Board Level Power Package Information • Surface Mountable 0.87” x 0.65” x 0.265” package • Weight = 7.8 grams Cool-Power® Rev 1.6 vicorpower.com Page 1 of 26 02/2015 800 927.9474 PI31xx-00-HVMZ Contents Contents Page Order Information 3 Absolute Maximum Ratings 4 Functional Block Diagram 5 Pin Description 6 Package Pin-Out 6 PI3108-00-HVMZ Electrical Characteristics 7 PI3109-00-HVMZ Electrical Characteristics 11 PI3106-00-HVMZ Electrical Characteristics 15 PI3111-00-HVMZ Electrical Characteristics 19 Functional Description 23 Input Power Pins 23 ENABLE 23 TRIM/SS 23 TM 24 SGND 24 Output Power Pins 24 Package Outline & Recommended PCB Land Pattern 25 Warranty Information 26 Cool-Power® Rev 1.6 vicorpower.com Page 2 of 26 02/2015 800 927.9474 PI31xx-00-HVMZ Order Information Transport Cool-Power VIN Vout Iout Max Package PI3108-00-HVMZ PI3109-00-HVMZ PI3106-00-HVMZ PI3111-00-HVMZ 16 - 50 V 16 - 50 V 16 - 50 V 16 - 50 V 3.3 V 5V 12 V 15 V 10 A 10 A 4.2 A 3.33 A 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” TRAY TRAY TRAY TRAY 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” 0.87” x 0.65” x 0.265” TRAY TRAY TRAY TRAY TRAY Media Also Available PI3101-00-HVIZ PI3105-00-HVIZ PI3110-01-HVIZ PI3109-01-HVIZ PI3106-01-HVIZ 36 - 75 V 36 - 75 V 41 - 57 V 18 - 36 V 18 - 36 V 3.3 V 12 V 18 V 5V 12 V 18 A 5A 3.3 A 10 A 4.2 A Cool-Power® Rev 1.6 vicorpower.com Page 3 of 26 02/2015 800 927.9474 PI31xx-00-HVMZ Absolute Maximum Ratings Name Rating +IN to -IN Max Operating Voltage -1.0 to 50 Vdc (operating) +IN to -IN Max Peak Voltage 55 Vdc (non-operating, 12.5ms) ENABLE to –IN -0.3 to 6.0 Vdc TM to –IN -0.3 to 6.0 Vdc TRIM/SS to –IN -0.3 to 6.0 Vdc +OUT to –OUT See relevant model output section Isolation Voltage (+IN/-IN to +OUT/-OUT) 2250 Vdc Continuous Output Current See relevant model output section Peak Output Current See relevant model output section Operating Junction Temperature -55 to 125°C Storage Temperature -65 to 125°C Case Temperature During Reflow 245°C Cool-Power® Rev 1.6 vicorpower.com Page 4 of 26 02/2015 800 927.9474 PI31xx-00-HVMZ Functional Block Diagram +OUT RUN BIAS START BIAS Synchronous Rectifier -OUT Vcc ZVS POWER TRAIN +IN Driver Driver ZVS POWER TRAIN ZVS Fast Current Limit + - -IN DC FB Output OVP + - FB DC + - DC + DC Timing Logic Reset Enable Period Ramp + - + On-Duty Ramp DC LFF ENB ENABLE +5V DC Slow Current Limit Input UVP + - + - 120us delay DC Input OVP + - CFB2 EA Fault RFB1 CFB1 DC 120us delay + - + - Over Temp DC FB + - Error Amp + DC TM ENB TRIM/SS RSS VREF 1.22V Temp Sensor CSS INT SGND Fault Cool-Power® Rev 1.6 vicorpower.com Page 5 of 26 02/2015 800 927.9474 Fault Latch And Reset Logic PI31xx-00-HVMZ Pin Description Pin Name Description +IN Primary side positive input voltage terminals. -IN Primary side negative input voltage terminals.

All faults will pull ENABLE low including over temperature. If increased turn on delay is desired, the ENABLE pin can be bypassed with a small capacitor up to a maximum of 1500 pF. Figure 41 — Picor PI31xx-00-HVMZ Shown With System Fuse, Filter, Decoupling And Extended Soft Start Input Power Pins IN(+) and IN(-) The input power pins on the PI31xx-00-HVMZ are connected to the input power source which can range from 16 V to 50 V DC. Under surge conditions, the PI31xx-00-HVMZ can withstand up to 55 V DC for 12.5 ms without incurring damage. The user should take care to avoid driving the input rails above the specified ratings. Since the PI31xx-00-HVMZ is designed with high reliability in mind, the input pins are continuously monitored. If the applied voltage exceeds the input over-voltage trip point (typically 53.5 V) the conversion process shall be terminated immediately. The converter initiates softstart automatically within 80ms after the input voltage is reduced back to the appropriate value. The input pins do not have reverse polarity protection. If the PI31xx-00-HVMZ is operated in an environment where reverse polarity is a concern, the user should consider using a polarity protection device such as a suitably rated diode. To avoid the high losses of using a diode, the user should consider the much higher efficiency Picor family of intelligent Cool-ORing® solutions that can be used in reverse polarity applications. Information is available at vicorpower.com. The PI31xx-00-HVMZ will draw nearly zero current until the input voltage reaches the internal start up threshold. If the ENABLE pin is not pulled low by external circuitry, the output voltage will begin rising to its final output value about 80ms after the input UV lockout releases. This will occur automatically even if the ENABLE pin is floating. To help keep the source impedance low, the input to the PI31xx-00-HVMZ should be bypassed with (2) 4.7uF 50 V ceramic capacitors of X7R dielectric in parallel with a low Q 100uF 63 V electrolytic capacitor. To reduce EMI and reflected ripple current, a series inductor of 0.2 to 0.47 uH can be added. The input traces to the module should be low impedance configured in such a manner as to keep stray inductance minimized. ENABLE The ENABLE pin serves as a multi-function pin for the PI31xx-00-HVMZ. During normal operation, it outputs the on-board 4.9 V regulator which can be used for trimming the module up. The ENABLE pin can also be used as a remote enable pin either from the secondary via an optocoupler and an external isolated bias supply or from the primary side through a small signal transistor, FET, or any device that sinks 3.3 mA, minimum. If the ENABLE pin is lower than 2.35 V typical, the converter will be held off or shut down if already operating. A third feature is offered in that during a fault condition, such as output OVP, input UV or OV, or output current limit, the ENABLE pin is pulled low internally. This can be used as a signal to the user that a fault has occurred. Whenever the ENABLE pin is pulled low, the TRIM/SS pin follows, resetting the internal and TRIM/SS Pin The TRIM/SS pin serves as another multi-purpose pin. First, it is used as the reference for the internal error amplifier. Connecting a resistor from TRIM/SS to SGND allows the reference to be margined down by as much as -20%. Connecting a resistor from TRIM/SS to ENABLE will allow the reference and output voltage to be margined up by 10%. If the user wishes a longer start up time, a small ceramic capacitor can be added to TRIM/SS to increase it. It is critical to connect any device between TRIM/SS and SGND and not -IN, otherwise high frequency noise will be introduced to the reference and possibly cause erratic operation. Referring to the figures below, the appropriate trim up or trim down resistor can be calculated using the equivalent circuit diagram and the equations. When trimming up, the trim down resistor is not populated. When trimming down, the trim up resistor is not populated. The soft start time is adjustable within the limits defined by the data tables and has a default value of 500us to reach steady state. The internal soft start capacitor value is 10nF.

Because of this, it is a good indicator of a thermal overload condition. The output is a scaled, buffered analog voltage which indicates the internal temperature in degrees Kelvin. Upon a thermal overload, the TM pin is pulled low, indicating a thermal fault has occurred. Upon restart of the converter, the TM pin reverts back to a buffered monitor. The thermal shutdown function of the PI31xx00-HVMZ is a fault feature which interrupts power processing if a certain maximum temperature is exceeded. TM can be monitored by an external microcontroller or circuit configured as an adaptive fan speed controller so that air flow in the system can be conveniently regulated. SGND The PI31xx-00-HVMZ SGND pin is the “quiet” control circuitry return. It is basically an extension of the internal signal ground. To avoid contamination and potential ground loops, this ground should NOT be connected to -IN since it is already star connected inside the package. Connect signal logic to SGND, not -IN. Output Power Pins +OUT And -OUT The output power terminals OUT(+) and OUT(-) deliver the maximum output current from the PI31xx-00-HVMZ through the Jlead output pins. This configuration allows for a low impedance output and should be connected to multi-layer PCB parallel planes for best performance. Due to the high switching frequency, output ripple and noise can be easily attenuated by adding just a few high quality X7R ceramic capacitors while retaining adequate transient response for most applications. The PI31xx-00-HVMZ does not require any feedback loop compensation nor does it require any opto-isolation. All isolation is contained within the package. This greatly simplifies the use of the converter and eliminates all outside influences of noise on the quality of the output voltage regulation and feedback loop. It is important for the user to minimize resistive connections from the load to the converter output and to keep stray inductance to a minimum for best regulation and transient response. The very small size footprint and height of the PI31xx-00-HVMZ allows the converter to be placed in the optimum location to allow for tight connections to the point of load. For those applications absolutely requiring very tight regulation, contact Picor Engineering at vicorpower.com for a remote sense application circuit which can be used.
