It is specifically designed to provide a controlled Factorized Bus distribution voltage for powering downstream VTM™ current multiplier — fast, efficient, isolated, low noise Point-of-Load (POL) converters. In combination, PRM modules and VTM modules form a complete DC-DC converter subsystem offering all of the unique benefits of Vicor’s Factorized Power ArchitectureTM (FPATM) : high density and efficiency; low noise operation; architectural flexibility; extremely fast transient response; and elimination of bulk capacitance at the Point-of-Load (POL). In FPA systems, the POL voltage is the product of the Factorized Bus voltage delivered by the PRM module and the "K-factor" (the fixed voltage transformation ratio) of a downstream VTM module. The PRM regulator controls the Factorized Bus voltage to provide regulation at the POL. Because VTM modules perform true voltage division and current multiplication, the Factorized Bus voltage may be set to a value that is substantially higher than the bus voltages typically found in "intermediate bus" systems, reducing distribution losses and enabling use of narrower distribution bus traces. A Military PRM module-VTM module chip set can provide up to 100 A or 115 W at a FPA system density of 169 A/in3 or 195 W/in3 — and because the PRM module can be located, or "factorized," remotely from the POL, these power densities can effectively be doubled. The Military PRM module described in this data sheet features a unique "Adaptive Loop" compensation feedback: a single wire alternative to traditional remote sensing and feedback loops that enables precise control of an isolated POL voltage without the need for either a direct connection to the load or for noise sensitive, bandwidth limiting, isolation devices in the feedback path.

The PRM monitors its output current and automatically adjusts its output voltage to compensate for the voltage drop in the output resistance of the VTM. ROS sets the desired value of the VTM output voltage, Vout; RCD is set to a value that compensates for the output resistance of the VTM (which, ideally, is located at the point of load).

PRMs have internal over / undervoltage lockout functions that prevent operation outside of the specified input range. PRMs will turn on when the input voltage rises above its undervoltage lockout. If the input voltage exceeds the overvoltage lockout, PRMs will shut down until the overvoltage fault clears. PC will toggle indicating an out of bounds condition. AL Version 4 +OUT +Out / -Out Factorized Voltage Output Ports These ports provide the Factorized Bus voltage output. The –Out port is connected internally to the –In port through a current sense resistor. The PRM has a maximum power and a maximum current rating and is protected if either rating is exceeded. Do not short –Out to –In. –OUT TM – Factory Use Only IL – Current Limit Adjust The PRM has a preset, maximum, current limit set point. The IL port may be used to reduce the current limit set point to a lower value. See “adjusting current limits” on page 10. PR – Parallel Port The PR port signal, which is proportional to the PRM output power, supports current sharing of two PRMs. To enable current sharing, PR ports should be interconnected. Steps should be taken to minimize coupling noise into the interconnecting bus. Terminate this port with a 10 k equivalent resistance to SG, e.g. 10 k for a single PRM, 20 k each for 2 PRMs in parallel, 30 k each for 3 PRMs in parallel etc.. Please consult Vicor Applications Engineering regarding additional considerations when paralleling more than two PRMs. VH – Auxiliary Voltage VH is a gated (e.g. mirrors PC), non-isolated, nominally 9 Volt, regulated DC voltage (see “Auxiliary Pins” specifications, on Page 7) that is referenced to SG. VH may be used to power external circuitry having a total current consumption of no more than 5 mA under either transient or steady state conditons including turn-on. 2 1 VC A A SC B B PC SG C C TM OS NC D D IL E E NC CD F F PR G G H H J J K K L L M M N N P P +IN –IN Bottom View Signal Name +In –In VC PC TM IL PR VH SC SG OS CD +Out –Out VC – VTM Control The VTM Control (VC) port supplies an initial VCC voltage to downstream VTMs, enabling the VTMs and synchronizing the rise of the VTM output voltage to that of the PRM. The VC port also provides feedback to the PRM to compensate for voltage drop due to the VTM output resistance. The PRM’s VC port should be connected to the VTM VC port. A PRM VC port can drive a maximum of two (2) VTM VC ports. PC – Primary Control The PRM voltage output is enabled when the PC pin is open circuit (floating). To disable the PRM output voltage, the PC pin is pulled low. Open collector optocouplers, transistors, or relays can be used to control the PC pin. When using multiple PRMs in a high power array, the PC ports must be tied together to synchronize their turn on. During an abnormal condition the PC pin will pulse (Fig.14) as the PRM initiates a restart cycle. This will continue until the abnormal condition is rectified. The PC should not be used as an auxiliary voltage supply, nor should it be switched at a rate greater than 1 Hz. 3 VH Designation G1-K1,G2-K2 L1-P1, L2-P2 A1,A2 B1, B2 C1, C2 D1, D2 F1, F2 A3, A4 B3, B4 C3, C4 D3, D4 F3, F4 G3-K3, G4-K4 L3-P3, L4-P4 Figure 17 — PRM pin configuration SC – Secondary Control The load voltage may be controlled by connecting a resistor or voltage source to the SC port referenced to SG. The slew rate of the output voltage may be controlled by controlling the rate-of-rise of the voltage at the SC port (e.g., to limit inrush current into a capacitive load). SG – Signal Ground This port provides a low inductance Kelvin connection to –In and should be used as reference for the OS, CD, SC,VH and IL ports. OS – Output Set The application-specific value of the Factorized Bus voltage (Vf) is set by connecting a resistor between OS and SG. Resistor value selection is shown in Table 1 on Page 2, and described on Page 9. If no resistor is connected, the PRM output will be approximately one volt. If set resistor is not collocated with the PRM, a local bypass capacitor of ~200 pF may be required. CD – Compensation Device Adaptive Loop control is configured by connecting an external resistor between the CD port and SG. Selection of an appropriate resistor value (see Equation 2 on Page 9) configures the PRM to compensate for voltage drops in the equivalent output resistance of the VTM and the PRM-VTM distribution bus. If no resistor is connected to CD, the PRM will be in Local Loop mode and will regulate the +Out / –Out voltage to a fixed value.

If this threshold is exceeded the output shuts down and a restart sequence is initiated, also indicated by PC pulsing. If the condition that causes OVP is still present, the unit will again shut down. This cycle will be repeated until the fault condition is removed. The OVP set point may be set at the factory to meet unique high voltage requirements. The current limit can be lowered by placing an external resistor between the IL and SG ports (see Figure 20 for resistor values). With the IL port open-circuit, the current limit is preset to be within the range specified in the output specifications table on Page 4. 22uF (ESR >= 1.7Ω) & 33uf (ESR>= 1.35Ω) & 47uF (ESR >= 1.1Ω) - NO IL TRIM As shown in Figure 19, the MP028F036M12AL is rated to deliver 3.3 A maximum, when it is delivering an output voltage in the range from 26 V to 36 V, and 120 W, maximum, when delivering an output voltage in the range from 36 V to 55 V. When configuring a PRM for use with a specific VTM, refer to the appropriate VTM data sheet. The VTM input power can be calculated by dividing the VTM output power by the VTM efficiency (available from the VTM data sheet). The input power required by the VTM should not exceed the output power rating of the PRM. 100 10 1 10uF (ESR >= 2.40Ω) Outside of Viable Trim Range PRM Output Power Versus VTM Output Power RIL Resistance (KΩ) 1000 75% 0uF 80% 85% 90% 95% 100% % Percentage of Current Limit Setpoint 4.00 3.80 Figure 20 — RIL vs percentage of current limit.

Exceeding this limit may cause the internal OVP set point to be exceeded. Product Safety Considerations If the input of the PRM is connected to SELV or ELV circuits, the output of the PRM can be considered SELV or ELV respectively. If the input of the PRM is connected to a centralized DC power system where the working or float voltage is above SELV, but less than or equal to 75 V, the input and output voltage of the PRM should be classified as a TNV-2 circuit and spaced 1.3 mm from SELV circuitry or accessible conductive parts according to the requirements of UL60950-1, CSA 22.2 60950-1, EN60950-1, and IEC60950-1. Parallel Considerations The PR port is used to connect two PRMs in parallel to form a higher power array. When configuring arrays, PR port interconnection terminating impedance is 10 k to SG. See note Page 8 and refer to Application Note AN002. Additionally one PRM should be designated as the master while all other PRMs are set as slaves by shorting their SC pin to SG. The PC pins must be directly connected (no diodes) to assure a uniform start up sequence.
