C 06/16/2015 Page 6 MCOTS-N-28V-60-HG Output: 9-60 V Current: 40A BASIC OPERATION AND FEATURES This converter consists of integrated buck and boost converters, both controlled simultaneously by a digital controller. It automatically changes operating mode (buck mode or boost) when the line voltage or output set point changes. Very high efficiency is maintained over wide input and output ranges by shifting operational modes and use of synchronous rectifiers. The converter runs at a fixed frequency with a predictable EMI performance. This half-brick converter uses the industry standard footprint and pin-out configuration. A typical V-I characteristic, with Vsetpoint=50V and Isetpoint=28A, when operating from Vin=30V, is shown in Figure A.

For noise immunity, the input has 0.1V hysteresis. It can be driven by any standard logic gate. The input has an internal 5KΩ pull-up to 3.3V; if unused, leave this input floating or tie it directly to Vsense-. Output Voltage (V) 50 Vin=40V Increase Vsetpoint 40 Increasing Vin Vin=30V 30 Vin=20V 20 Vin=10V 10 Increase Isetpoint 0 0 5 10 15 20 25 Output Current (A) 30 35 40 45 Figure A CONTROL FEATURES REMOTE ON/OFF: Only Negative On/Off logic is available in the converter series: logic high at the input turns the converter Off while a logic low turns in On. Timing of this is shown in Figures 7, 8. A high level can be driven to any voltage between 1.5V and 3.3V, or simply left floating as the unit contains an internal 10KΩ pull-up to 3.3V. The pin can be pulled low (to Vsense-) by an optocoupler, an opensource/drain transistor or wired permanently to Vsense-. To provide noise immunity the input has 0.3V of hysteresis. OUTPUT VOLTAGE SETPOINT: The output voltage can be programmed to any voltage between 0 V dc and Vmax by connecting one resistor between the Vset pin (6) and Vsense- (5); See Figure C. For a desired output voltage, the value of the resistor should be: Rvset(Vset) = [( 11830 x Vmax Vset + 0.058 x Vmax ) -10912 ] (Ω) Multiple units that have a common Vsense- connection can be controlled by the same On/Off signal, but it is recommended that a small schottky diode be added to each input as shown in Figure B.

See Figure 10 for the large scale dynamics of this input. PROTECTION FEATURES Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled “Input System Instability”. The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn-On Voltage Threshold value (listed on the specification page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off. where: Vset = desired output voltage setpoint Vmax = maximum rated output voltage (60V) Output Current Shutdown: To provide protection in an output short condition, the unit is equipped with internal short circuit protection. When the short-circuit protection is triggered, the converter shuts down and then waits an inhibit time (~100ms), after which it tries to turn on again. If the short condition remains, the current limit circuit will limit the output current. The unit will return to normal operation once the fault condition is removed. OUTPUT CURRENT SETPOINT: The maximum output current (effectively the current limit) can be reduced to any value between 0 and Imax by connecting one resistor between the Iset pin (B) and Vsense- (5); see Figure C. The value of the resistor should be: Internal Over-Voltage Protection: To fully protect from excessive output voltage, the unit contains an output over-voltage shutdown that is fixed at ~110% of Vmax. If this limit is reached, the converter shuts down and then waits an inhibit time (~100ms), after which it restsarts. Vvset(Vset) = 2.366 – 2.316 ( Vset Vmax ) See Figure 9 RIset(Iset) = [( 0.0469 Imax + Iset 1.153 Imax - Iset ) ] *10200 -10 (Ω) Alternatively, the Iset pin can be driven from an external voltage source: Viset(Iset)= where: ( 0.0953+2.085 * Iset/Imax ) Over-Temperature Shutdown: Two sensors in the module monitor the temperature of both the buck and boost sections. When the temperature at either sensor exceeds the Over Temperature Shutdown value, the converter is disabled. It will restart normally when it then cools by the amount of the Over-Temperature Shutdown Hysteresis. V Iset = desired output current setpoint Imax = maximum rated output current (40A) Undriven, the Iset pin floats to 2.5V which sets the current limit at its nominal value of 115%*Imax. See Figure 12 for the large signal dynamics of this control. Product # MCOTS-N-28V-60-HG Phone 1-888-567-9596 www.synqor.com Doc.# 005-0006571 Rev. C 06/16/2015 Page 8 MCOTS-N-28V-60-HG Output: 9-60 V Current: 40A APPLICATION CONSIDERATIONS Cin2 Input filtering: These modules should be connected to a low-impedance source. A highly inductive source can affect the stability of the module. An input capacitor must be placed adjacent to the input pins of the module to minimize input ripple voltage and ensure stability. See SynQor’s application note titled Input System Stability for guidance on selecting appropriate input filter elements. http://www.synqor.com/documents/appnotes/appnt_System_Instability.pdf Output capacitance: An output capacitor of at least 100uF with an ESR of ~50mOhms is recommended to damp the resonance of the output filter. More capacitance can be added to improve dynamic response to load variation; there is not upper limit on the value of the output capacitance. Very large output capacitors may slow the converter’s start up time due to the current required to charge them being limited by current limit or Isetpoint.

Vin+ +Vin On/Off Remote sense: In the event of an open sense line, the module maintains output voltage regulation via internal resistors between its Vsense+ and +Vout, and Vsense- and -Vout pins. To avoid damaging those resistors, maintain the voltage differentials to within the limits in ABSOLUTE MAXIMUM RATINGS at all times. Ishare Current limit: Available current is limited by maximum output current in buck mode (Vin>Vout), and by maximum input current in boost mode (Vin<Vout). +Vin +Vout MCOTS HVNQ DC-DC Converter Vout+ Vset Rvset Cout Vsense-Vout -Vin Vout- Cin On/Off Ishare for Vin >Vout Ilimit = 1.12 x Imax (Amps) +Vout MCOTS Vsense+ HVNQ Vset DC-DC Converter +Vout MCOTS Vsense+ HVNQ Vset DC-DC Converter -Vin Rvset Vsense-Vout for Vin < Vout where Imax = Maximum rated output current ( Ilimit = 1.12 x Imax Vin Vout ) (Amps) Generating Negative output voltage (inversion): The circuit shown in Figure D can be used to generate a negative output voltage from a positive input.

The units should all be set at the same output voltage setpoint by using identical Rvset resistors. In this arrangement, the level of the Ishare/Imon bus is that of the average current delivered by each converter. Doc.# 005-0006571 Rev.
