Each model has a wide input voltage range (4.7 - 13.8 V) and offers a wide 0.8375 - 5.1 V output voltage range with a 80 A load. An external resistor adjusts the output voltage from its pre-set value of 0.8375 V to any value up to the maximum allowed value for that model. The SIL/SMT80C2 offers remote ON/OFF and over-current protection as standard. Technical Reference Note Embedded Power for Business-Critical Continuity Rev. 04.25.11 SIL/SMT80C2 2 of 20 General Description Electrical Description The SIL/SMT80C2 is implemented using a multi-phase synchronous buck topology. A block diagram of the converter is shown in Figure 1. The output is adjustable over a range of 0.8375-5.1 V by using a resistor from the trim pin to -trim pin, or by driving the TRIM pin with a voltage. SIL80C2 Vin Vout Phase 1 Upper G/Drive Tri m Ilimit PWRGD The converter can be shut down via the enable pin. This input is run with positive logic that is compatible with popular logic devices. Positive logic implies that the converter is enabled if the input is high (or floating), and disabled if it is low.

Wide Operating Temperature Range The SIL/SMT80C2's ability to accommodate a wide range of ambient temperatures is the result of its extremely high power conversion efficiency and resultant low power dissipation, combined with the excellent thermal performance of the PCB substrate. Maximum output power that the module can deliver depends on a number of parameters, primarily: Ishare Enable On/Off Power Good 4 Vout 15,16,18, 20,22,24 11 +Sense SIL80C2 6 9 R uvlo Vin 12-14 3,7,8,17, 19,21,23 1 C in GND 5 R trim 10 C out R L O A D -Sense GND • • • • Input voltage range Output load current Figure 2 - Standard Application Drawing Air velocity (forced or natural convection) Mounting orientation of target application PCB, i.e., vertical/horizontal mount, or mechanically tied down (especially important in natural convection conditions). • Target application PCB design, especially ground planes. These can be effective heatsinks for the converter. The SIL/SMT80C2 module has an operating temperature range of 0 °C to 85 °C with suitable derating and/ or forced air cooling. Technical Reference Note Embedded Power for Business-Critical Continuity Rev. 04.25.11 SIL/SMT80C2 3 of 20 Features and Functions Output Voltage Adjustment The output voltage on all models is adjustable from 0.8375-5.1 V. Undervoltage Lockout The default undervoltage lockout is set at 4.7 V. Current Limit and Short-Circuit Protection The SIL/SMT80C2 model has a built-in non-latching current limit function and continuous short-circuit protection. When an overcurrent condition occurs, the module goes into hiccup mode, where it attempts to power up periodically to determine if the problem persists. Note that none of the module specifications are guaranteed when the unit is operated in an overcurrent condition. Enable The enable pin allows external circuitry to put the SIL/SMT80C2 converter into a low dissipation standby mode. Positive logic enable pin is available as standard. The unit is turned on if the enable pin is high (or floating). Pulling the pin low will disable the unit. To guarantee turn-on, the enable voltage must be above 1.25 V. To disable, the enable voltage must be pulled below 0.7 V. Figures 3 and 4 show various circuits for driving the Enable feature. The Enable input can be driven through a discrete device (i.e. a bipolar signal transistor) or directly from a logic gate output. The output of the logic gate may be an open-collector (or open-drain) device.

This output pin uses positive logic and is open collector. Also, the power good output is able to sink 1 mA. The power good signal should not be pulled any higher than 5.1 V. When the output of the module is within ±10% of the nominal set point, the power good pin can be pulled high. Overtemperature Protection (OTP) The SIL/SMT80C2 is equipped with non-latching overtemperature protection. A temperature sensor monitors the temperature of the PCB near one the main FETs. If the temperature exceeds a threshold of 150 °C (typical) the converter will shut down, disabling the output. When the substrate temperature has decreased by 10 °C the converter will automatically restart. The converter might experience overtemperature conditions during a persistent overload on the output. Overload conditions can be caused by external faults. OTP might also be entered due to a loss of control of the environmental conditions (e.g. an increase in the converter’s ambient temperature due to a failing fan). Technical Reference Note Embedded Power for Business-Critical Continuity Rev. 04.25.11 SIL/SMT80C2 5 of 20 Application Output Voltage Adjustment The output of the module can be adjusted, or trimmed, from 0.8375 V to 5.1 V. This is accomplished by connecting an external resistor between the Trim pin and -Trim as shown in Figure 5 or with a voltage as shown in Figure 6. Extremely high accuracy setpoints can be achieved with the use of a potentiometer as shown in Figure 7.

The trim equation for the external voltage configuration shown Figure 6 is: R Rtrim1 (1.2 - 2Vt) trim2(kΩ) = Rtrim1 (Vout - 0.8375) - 1.675 Where Vout is the desired output voltage, Rtrim1 and Rtrim2 are the resistors in Figure 6 and Vt is the applied external voltage. The trim equation for the potentiometer configurations shown in Figure 7 is: 0.8375 Vout = (Rtrim2 + Rpot)Rtrim1 X (2Rtrim2 + 2Rpot + Rtrim1Rtrim2 + Rtrim1Rpot + 2Rtrim1) Where Vout is the desired output voltage, Rtrim1 and Rtrim2 are the resistors in Figure 7 and Rpot is the resistance of the potentiometer. Undervoltage Lockout The SIL/SMT80C2 has built-in undervoltage lockout to ensure reliable output power. The lockout prevents the unit from operating when the input voltage is too low. The UVLO for the SIL/SMT80C2 can be adjusted with the following equation: The trim equation for the undervoltage lockout is: 124.8 + Vturn_on Ruvlo (kΩ) = 10 Vturn_on - 42.06 Technical Reference Note Embedded Power for Business-Critical Continuity Rev. 04.25.11 SIL/SMT80C2 7 of 20 Application (cont'd) Remote Sense Compensation The remote sense compensation feature minimizes the effect of resistance in the distribution system and facilitates accurate voltage regulation at the load terminals or another selected point. The remote sense lines will carry very little current and hence do not require a large cross-sectional area. However, if the sense lines are routed on a PCB, they should be located close to a ground plane in order to minimize any noise coupled onto the lines that might impair control loop stability. The module will compensate for a maximum drop of 400 mV. Remember that when using remote sense compensation all the resistance, parasitic inductance and capacitance of the distribution system are incorporated into the feedback loop of the power module. This can have an effect on the modules compensation capabilities, affecting its stability and dynamic response. Parallel Operation Parallel operation of multiple converters is available since the SIL/SMT80C2 has a current sharing option. The converter will share to within ±10% of full load. To current share, Pin 6 of each module should be connected. Also, the remote sense lines should be connected at the same point. Figure 9 shows the typical current sharing application.

No output capacitance is required for stable operation. When powering loads with large dynamic current requirements, improved voltage regulation is obtained by inserting low ESR capacitors as close as possible to the load. Low ESR ceramic capacitors will handle the short duration high frequency components of the dynamic current requirement. In addition, higher values of electrolytic capacitors should be used to handle the midfrequency components. It is equally important to use good design practices when configuring the dc distribution system. Low resistance and low inductance PCB layout traces should be utilized, particularly in the high current output section. Remember that the capacitance of the distribution system and the associated ESR are within the feedback loop of the power capabilities, thus affecting the stability and dynamic response of the module. Note that the maximum rated value of output capacitance varies between models and for each output voltage setpoint. A stability vs. Load Capacitance calculator, (see your sales representative), details how an external load capacitance influences the gain and phase margins of the SIL/SMT80C2. SMT Reflow Guidelines For a SnPb process: Pads should be above 183C (liquidus) for 90 seconds max (60-75 seconds typical) with a peak temperature of 225C. For a leadfree SAC305 process: pads should be above 217C (liquidus) for 90 seconds max (60-75 seconds typical) with a peak temperature of 250C. Water Washing Not recommended.
