Technical content

The DRQ 500W series provides a fully regulated, digitally controlled DC output in a ¼-brick format that will support the evolving Advanced Bus Con- verter (ABC) industry standard footprint for isolated board mounted power modules. The DRQ series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules. The DRQ series offers high output current (up to

43.5 Amps) in an industry standard “quarter brick”

package. The DRQ series is an isolated, regulated, 500W-11.5Vout quarter brick that supports the TNV input voltage range of 38V-75V with a typical effi ciency of 95.5%. Advanced automated surface mount assembly and planar magnetics deliver galvanic isolation rated at 2250 Vdc for functional insulation. Target markets include networking equipment, Power over Ethernet applications, wireless networking equip- ment, telecommunications equipment, wireless pre-amplifi ers, industrial and test equipment, and applications requiring a regulated 11.5V output. A wealth of self-protection features include input undervoltage lockout and overtemperature shut- down; over current protection using the “hiccup” autorestart technique provides indefi nite short- circuit protection, along with output OVP . The DRQ series is certifi ed to safety standards UL/IEC/CSA 60950-1, 2nd edition. It meets RFI/EMI conducted emission compliance to EN55022, CISPR22 with an external fi lter. PRODUCT OVERVIEW

The module includes over voltage limiting circuitry for protection of the load. voltage surpasses the OVP limit, the module can respond in different ways. The default response from an over voltage fault is to immediately shut down. and when the fault condition no longer exists the device will be re-enabled. it can be confi gured by MFR_PGOOD_POLARITY. to help alleviate bandwidth limitations related to continuous fault monitoring. The module supports 100 kHz and 400 kHz bus clock frequency only.

500W Digital Fully Regulated Intermediate DC-DC Bus Converter MDC_DRQ-12/42-D48.A03 Page 21 of 24 www.murata-ps.com/support Minimum Output Loading Requirements All models regulate within specifi cation and are stable under no load to full load conditions. Thermal Shutdown (OTP , UTP) To prevent many over temperature problems and damage, these converters include thermal shutdown circuitry. If environmental conditions cause the temperature of the DC-DCs to rise above the Operating Temperature Range up to the shutdown temperature, an on-board electronic temperature sensor will power down the unit. When the temperature decreases below the turn-on threshold set in the command recover temp is (OT_FAULT_LIMIT-MFR_OT_ FAULT_HYS), the hysteresis is defi ned in general electrical specifi cation section. The OTP and hysteresis of the module can be reconfi gured using the PMBus. The OTP and UTP fault limit and fault response can be confi gured via the PMBus. CAUTION: If you operate too close to the thermal limits, the converter may shut down suddenly without warning. Be sure to thoroughly test your applica- tion to avoid unplanned thermal shutdown. Temperature Derating Curves The graphs in this data sheet illustrate typical operation under a variety of conditions. The Derating curves show the maximum continuous ambient air temperature and decreasing maximum output current which is acceptable under increasing forced airfl ow measured in Linear Feet per Minute (“LFM”). Note that these are AVERAGE measurements. The converter will accept brief increases in current or reduced airfl ow as long as the average is not exceeded. Note that the temperatures are of the ambient airfl ow, not the converter itself which is obviously running at higher temperature than the outside air. Also note that “natural convection” is defi ned as very fl ow rates which are not using fan-forced airfl ow. Depending on the application, “natural convection” is usually about 30-65 LFM but is not equal to still air (0 LFM). Murata Power Solutions makes Characterization measurements in a closed cycle wind tunnel with calibrated airfl ow. We use both thermocouples and an infrared camera system to observe thermal performance. As a practical matter, it is quite diffi cult to insert an anemometer to precisely measure airfl ow in most applications. Sometimes it is possible to estimate the effective airfl ow if you thoroughly understand the enclosure geometry, entry/exit orifi ce areas and the fan fl owrate specifi cations. CAUTION: If you exceed these Derating guidelines, the converter may have an unplanned Over Temperature shut down. Also, these graphs are all collected near Sea Level altitude. Be sure to reduce the derating for higher altitude. Output Short Circuit Condition The short circuit condition is an extension of the “Current Limiting” condition. When the monitored peak current signal reaches a certain range, the PWM controller’s outputs are shut off thereby turning the converter “off.” This is followed by an extended time out period. This period can vary depending on other conditions such as the input voltage level. Following this time out period, the PWM controller will attempt to re-start the converter by initiating a “normal start cycle” which includes softstart. If the “fault condition” persists, another “hiccup” cycle is initiated. This “cycle” can and will continue indefi nitely until such time as the “fault condition” is removed, at which time the converter will resume “normal operation.” Operating in the “hiccup” mode during a fault condition is advantageous in that average input and output power levels are held low preventing excessive internal increases in temperature. Remote On/Off Control The DRQ series modules are equipped with both primary (On/Off 1, enabled, pull up internal) and secondary (On/Off 2, disabled, pull up internal) control pins for increased system fl exibility. Both are confi gurable via PMBus. The On/Off pins are TTL open-collector and/or CMOS open-drain compatible. (See general specifi cations for threshold voltage levels. See also MFR_PRIMARY_ON_OFF_ CONFIG section.) Negative-logic models are on (enabled) when the On/Off is grounded or brought to within a low voltage (see specifi cations) with respect to –Vin. The device is off (disabled) when the On/Off is left open or is pulled high to +13.5Vdc with respect to –Vin. The On/Off function allows the module to be turned on/off by an external device switch. Positive-logic models are enabled when the On/Off pin is left open or is pulled high to +13.5V with respect to –Vin. Positive-logic devices are disabled when the On/Off is grounded or brought to within a low voltage (see specifi ca- tions) with respect to –Vin. For voltage levels for On/Off 2 signal see functional specifi cations. The restart delay for this module to turn On/Off by the On/Off control pin is 100ms. On/Off 1 can be confi gured by PMBus command MFR_PRIMARY_ON_OFF_ CONFIG (DDh); default confi guration is not ignored; required On/Off 1 control pin to be asserted to start the unit. On/Off 2 can be confi gured by PMBUS command ON_OFF_CONFIG (02h); default confi guration is ignored; treat it as always ON. DRQ's On/Off status is dependent on On/Off 1 control, On/Off 2 control, and OPERATION (PMBus command) status; all three must be ON to turn DRQ on; if one of them is OFF, unit will be turned off. Output Capacitive Load These converters do not require external capacitance added to achieve rated specifi cations. Users should only consider adding capacitance to reduce switching noise and/or to handle spike current load steps. Install only enough capacitance to achieve noise objectives. Excess external capacitance may cause degraded transient response and possible oscillation or instability. Remote Sense Input Use the Sense inputs with caution. Sense is normally connected at the load. Sense inputs compensate for output voltage inaccuracy delivered at the load. This is done by correcting IR voltage drops along the output wiring and the current carrying capacity of PC board etch. This output drop (the difference between Sense and Vout when measured at the converter) should not exceed 0.5V. Consider using heavier wire if this drop is excessive. Sense inputs also improve the stability of the converter and load system by optimizing the control loop phase margin. Note: The Sense input and power Vout lines are internally connected through low value resistors to their respective polarities so that the converter can operate without external connection to the Sense. Nevertheless, if the Sense function is not used for remote regulation, the user should connect +Sense to +Vout and –Sense to –Vout at the converter pins.
