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 Architecture™ (FPA™) : 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 module monitors its output current and automatically adjusts its output voltage to compensate for the voltage drop in the output resistance of the VTM module. R OS sets the desired value of the VTM module output voltage, VOUT ; R CD is set to a value that compensates for the output resistance of the VTM module (which, ideally, is located at the point of load). For selection of R OS and R CD, refer to Table 1 below or Page 9. The V•I Chip module’s bi-directional VC port : 1. Provides a wake up signal from the PRM module to the VTM module that synchronizes the rise of the VTM module output voltage to that of the PRM module. 2.

PRM™ modules have internal overvoltage / undervoltage lockout functions that prevent operation outside of the specified input range. PRM modules will turn on when the input voltage rises above its undervoltage lockout. If the input voltage exceeds the overvoltage lockout, PRM modules will shut down until the overvoltage fault clears. PC will toggle indicating an out of bounds condition. +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 module has a maximum power and a maximum current rating and is protected if either rating is exceeded. Do not short –Out to –In. VC – VTM Control The VTM Control (VC) port supplies an initial VCC voltage to downstream VTM™ modules, enabling the VTM modules and synchronizing the rise of the VTM module output voltage to that of the PRM module. The VC port also provides feedback to the PRM module to compensate for voltage drop due to the VTM module output resistance. The PRM module’s VC port should be connected to the VTM module VC port. A PRM module VC port can drive a maximum of two (2) VTM module VC ports. PC – Primary Control The PRM module voltage output is enabled when the PC pin is open circuit (floating). To disable the PRM module 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 PRM modules in a high power array, the PC ports should be tied together to synchronize their turn on. During an abnormal condition the PC pin will pulse (Fig.12) as the PRM module 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. TM – Factory Use Only IL – Current Limit Adjust The PRM regulator 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 limit” 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.

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 and Table 1 on Page 2) 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. vicorpower.com 800-735-6200 PRM™ Regulator MP028F036M12AL Rev. 3.3 Page 8 of 14 Application Information V•I Chip Regulator Regulator 0.01 µF VC PC TM IL NC PR VH SC SG OS NC CD Current Multiplier VF = ROS RCD (IL•Ro) VL + K K +In +Out 10 kΩ PRM™-AL +In +Out +Out 0.4 µH TM VC PC VTM™ – Out VIN –In –Out 10 Ω – In K Ro L O A D – Out Figure 16 — Adaptive Loop compensation with soft start using the SC port.

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. PRM™ Regulator Output Power Versus VTM™ Current Multiplier Output Power As shown in Figure 17, 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 50 V. When configuring a PRM™ module for use with a specific VTM™ module, refer to the appropriate VTM module data sheet. The VTM current multiplier input power can be calculated by dividing the VTM module output power by the VTM module efficiency (available from the VTM module data sheet). The input power required by the VTM module should not exceed the output power rating of the PRM module. 4.00 3.80 3.60 3.40 3.20 3.00 V•I Chip Regulator Adjusting Current Limit The current limit can be lowered by placing an external resistor between the IL and SG ports (see Figure 18 for resistor values).

Always ascertain and observe the safety, regulatory, or other agency specifications that apply to your specific application. Product Safety Considerations If the input of the PRM module is connected to SELV or ELV circuits, the output of the PRM module can be considered SELV or ELV respectively. 0 ~ ~ 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 Factorized Bus Voltage (VF) Figure 17 — MP028F036M12AL rating based on Factorized Bus voltage The Factorized Bus voltage should not exceed an absolute limit of 55 V, including steady state, ripple and transient conditions. Exceeding this limit may cause the internal OVP set point to be exceeded. Parallel Considerations The PR port is used to connect two PRM modules 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 module should be designated as the master while all other PRM modules 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. Consult Vicor applications engineering for applications requiring more than two PRM modules.
