Technical Specification IQ65033QGA12 34-75 V @ 12A 3.3 V & 5.0 V Quarter-brick ATCA Input / Output MGMT Power Power Interface Module The IQ65033QGA12 iQor Power Interface Module integrates all features required by the AdvancedTCA Base Specification into a Quarter-Brick footprint. The iQor offers industry leading external hold-up capacitor volumetric density for a compact overall solution. At 90V hold-up capacitor voltage (trimmable 50-95 V), only 564 uF is required to achieve 8.70ms hold-up time at 200Win. The -48 V output voltage is conditioned for smooth operation through severe input transient events. The iQor is designed thermally and electrically to drive higher power wide-range-input DC/DC converters such as the 400W SynQor PQ60120QZB33. RoHS Compliant (see last page).

B 09/06/2012 Page 7 Input:34-75 V Outputs:3.3 V & 5.0 V Current:12A Package:Quarter-brick Application Section FEATURE DESCRIPTIONS Input ORing MOSFETs: ORing of dual -48V feeds is provided by four MOSFETs, which are individually controlled so as to operate as an ideal diode (see Figure A). If there is an input feed short of any kind, a control circuit will detect reverse current and turn off the MOSFET in 250ns (typ.), to avoid disturbing the other feed voltage. At zero current, the MOSFET is guaranteed to be off. In the case of a fuse failure, this triggers the ALARM output, due to an apparent input feed loss. Current hysteresis prevents limit cycling around the transition point between body diode and MOSFET conduction. Due to the ‘Turn On Current’ feature, at fixed Input- Voltages the Output Voltage will experience one or two Diode drops (0.6V or 1.2V) for currents at or below ‘Turn On Current’ thresholds. External Input Fuse Failure Detection: At zero current, the input ORing MOSFETs are guaranteed to be off. In the case of a fuse failure, an on-board bleed resistor pulls the input feed voltage down. This triggers the ALARM output due to an apparent input feed loss. There are two main down-sides to this approach. First, there is no way to distinguish between a feed loss and a fuse failure. Second, an enable fuse loss is not detected, since the enables are diode OR’d. The full featured version of the iQor offers additional data reporting that makes full fuse detection possible. Among other data, each feed voltage and each enable voltage is reported through the I2C port. These voltages can be compared with the voltages reported by the shelf manager to determine whether any board fuse is blown. ALARM Output: The ALARM pin gives an external indication of a fault condition. It is an isolated and buffered open-collector output, which is normally pulled low. In the presence of an input feed loss (which can be caused by a fuse failure), the ALARM output will be tri-stated. 5 6 ENABLE_A HU_CAP 18 ENABLE_B VRTN_A 3 Temp sense Enable Logic FET control 4 Input Enable: The ENABLE_A/B signals connect to VRTN_A/B on the backplane via the shortest pins in the zone 1 connector. They are the last pins to mate during board insertion, and the first to disconnect during board extraction. The ENABLE_A and ENABLE_B signals are diode-ORed together which lets either signal enable the module. Whenever both ENABLE pins are open, the hot-swap switch is opened. This prevents -48V output power from being drawn though the EARLY pre-charge resistors.

On board insertion, the management power remains off until at least one of ENABLE_A/B is connected. On board extraction, the management power is disabled at the end of the 100ms hold-up period, and remains off until ENABLE_A/B is reconnected. This prevents the IPMI controller from reading an invalid hardware address when a board is partially inserted. Management power flows through the EARLY pre-charge resistors for a maximum of 100ms, which provides a margin similar to the pre-charge event in terms of resistor safe-operating-area. 48V Input voltage 0 Holdup time, tH Holdup event 48V 35V typ. (12A DS Version only) Payload output 48V 0 Thresholds at -48Vout EARLY Precharge Resistors: The EARLY_A/B signals connect to the longest pins in the zone 1 power connector, and therefore first to mate during board insertion. External resistors connected between these signals and -48V (A and B) allow the relatively small EMI filter capacitance to be pre-charged before the main power pins make contact.

B 09/06/2012 Page 9 Input:34-75 V Outputs:3.3 V & 5.0 V Current:12A Package:Quarter-brick Application Section 48V Hot Swap - Over-Current Protection: If the -48V output current rises above the current limit threshold, the hot-swap switch will be disabled, and will immediately enter another soft-start sequence. If an output short is detected, the hot-swap switch will be disabled and will enter a hiccup mode of operation with automatic restart. 0V High Enable A/B The full featured version of the iQor reports actual output current through the I2C port. The iQor unit conditions the -48V output, providing for seamless ridethrough of input voltage transients. If the positive dV/dt of the input voltage is too high, the hot-swap switch will be disabled and will immediately enter another soft-start sequence. This limits the dV/dt seen on the -48V output, which prevents the 12V payload power converter from having such a large glitch on its output that it shuts down. The -48V output hold-up function remains active throughout, in case the hot-swap switch is forced off for too long. Passive Transient Suppression: Each input feed has a dedicated internal bidirectional TVS zener diode, rated for a minimum clamp voltage of 77.8V at 1mA. A TVS diode short due to electrical overstress will not disable the iQor module: a fuse will open, and the module can continue to run from the other feed. External Hold-up Capacitor Charge: A current controlled DC-DC converter charges the external hold-up capacitor to a voltage of 50V-95V, set by an external resistor. The charge voltage can range either above or below the input feed voltage. Constant current charging takes place whenever the hot-swap switch is enabled. Hold-up Capacitor Connect: When the hot-swap switch is enabled, 2 seconds are allocated to charge the hold-up capacitor. After this time, a comparator is armed, which connects the hold-up capacitor to the -48V output should the output ever drop below the given connect threshold. A current limit circuit protects against damage during a short circuit condition. A dV/dt limit circuit regulates the hold-up connect switch turn-on speed. When the comparator is tripped, the hold-up connect switch remains closed for 100ms, is off for 2 seconds to allow the hold-up capacitor to recharge, and then is automatically rearmed (if the output voltage is above the given arm threshold). Hold-up Capacitor Discharge: Whenever the hot-swap switch is disabled, an internal resistor bank is connected across the hold-up capacitor. This is intended to reduce the voltage on the hold-up capacitor below 60V within 1 second. Management Power: An isolated management power converter delivers both 3.3V and a low power 5.0V relative to LOGIC_GND. Overcurrent protection operates in constant current with a hiccup mode if the output voltage drops too far. Output over-voltage circuitry is included with a redundant reference and optocoupler.

Notes: • Time relationships shown have tolerance defined in the specifications table. • Hot Swap switch output is not available to the user for monitoring • Power up inrush duration is typical with Early mate resistor of 100 Ohms. Figure D: Power up (Board insertion) timing diagram In the event of a gradual loss of input voltage (Fig. C), the main -48Vout will shut down 100ms after the beginning of the hold-up event. The -48Vout will enter a hiccup mode of operation for input voltages below the Hold-up Arm Threshold. Management power will continue to run until the input voltage (plus 0V to 1.2V for the ORing MOSFETs) decays to the management power under-voltage turn-off threshold. 20 PH=200W CF=100µF VI=-43V PH=Power at Holdup CF=Output Capacitor (Filter) VI=Voltage at Input 15 10 5 90V 80V 70V 0 The events from power up to availability of output voltage and full payload current are illustrated in the timing diagram shown in Figure D. Hot Swap – Shutdown Timing: In the event of a sudden loss of input voltage (see Figure B), a hold-up event will be triggered. When the output voltage (plus a diode drop for the hot-swap body diode) decays to the management power under-voltage turn-off threshold, the main -48V output and the 3.3V/5.0V outputs will shut down simultaneously. Low 3.3V, 5V outputs Hold-up Time (ms) Hot Swap - Transient Suppression: Input transient events can occur if there is a short on an adjacent board or backplane. The short builds up a large current in the wiring inductance, and when a fuse blows, the voltage behind the fuse spikes very quickly. This can cause a loss of redundancy since many other boards could be exposed to this spike.

However, this is not a square wave: the voltage starts at a minimum amplitude of -43V, falls at 50V/ms, remains at 0V for 5ms, and then rises at 12.5V/ms. At the worst case values of the hold-up connect threshold and the management power under-voltage lockout threshold, the required hold-up time is 8.70ms EXTERNAL HOLD-UP TRIM RESISTOR SELECTION Rtrim is the external hold-up trim resistance for a given desired nominal holdup capacitor charge voltage (VHU) (see Figure G): EXTERNAL HOLD-UP CAPACITOR VOLTAGE RATING Operating electrolytic capacitors near their voltage rating does not significantly affect their reliability, as it does with tantalum or ceramic type capacitors. The operating life of electrolytic capacitors is primarily determined by the capacitor internal temperature. The capacitor lifetime roughly doubles for every 10ºC reduction in internal temperature. SynQor recommends running 100V rated electrolytic capacitors at 90V, which dramatically increases hold-up time for a given capacitor volume (see Figure E). A built-in circuit automatically discharges the hold‑up capacitor when the input voltage is removed.

The actual analog parameter values are calculated by multiplying by the specified scaling factors (see Table 1). The status bits are interpreted in Table 2. The initial value of all registers is zero. Data in the registers begins updating 300 ms after management power startup, and continues updating at approximately 100 ms intervals during steady-state operation. All registers are updated simulatneously. I2C Protocol: Reading from any internal register of the iQor monitor requires that an internal (pseudo) register, Data_Pointer, be initialized prior to reading (see Figure I). Data_Pointer is write-only. It is written from the second byte of any I2C WRITE message (the first byte is the 7 bit I2C Address and the R√W bit). Subsequent data bytes in a WRITE message (3rd Byte and beyond) only increment Data_Pointer. Any READ message will return the value of the internal register referenced by Data_Pointer and increments Data_Pointer by one. For instance, if the master acknowledges (AK), the next internal register referenced by Data_Pointer will be returned and Data_Pointer will be incremented by one. This process is repeated until the master does not acknowledge (NACK) and issues a STOP bit.
