Pin 3 is a No Connect or it could be connected to Anode pin, pin 4.

Pin 5 is a No Conncect or it could be connected to Gate Drive pin, pin 6.

C13 Controls on/off time of CSD18531Q5A and powers the control circuitry when the FET is on.

FET should be chosen with low Rds(on), low gate charge, and a gate threshold maximum of 3V.

SMBJ28A-13-F will clamp the positive terminal to 40V typically.

SMBJ14A-13-F needs the lower clamp voltage. This is due to the 40V reverse voltage possibility, in addition to, dealing with a stored voltage on input capacitors.

TVS devices need to be placed close to the input connector.

12V_BATT_A and 12V_FILTERED_A rail only needs to withstand a maximum voltage of 40V. Therefore, the summation of caps in series could equal 50V by applying a 25% margin on 40V max voltage.

Capacitors in series voltage ratings were selected to reduce the amount of BOM line items.

12V_A Rail only needs 50V capacitors but C5 and C6 are selected as 100V to reduce the amount of BOM line items.

According to EMI filter calculations the electrolytic capacitors need to be at least 4x total input capacitance for a switch-mode power supply. See Design Considerations for calculation.

Ceramic input caps in series shall be placed in an "L" configuration. If the board bends, the ceramic caps may crack and cause a short. If one of the input caps shorts then the other cap in series (rotated 90 degrees on the board) will prevent a short on the power supply.

Disable / EN pin 3 has an internal 1 MOhm pulldown resistor to GND. Leaving the pin unconnected or connected to ground will enable the device. Using a 10k and a test point so that the device could be set to shutdown mode with external signal.

C50 allows the induced common-mode current a path to close the loop. This will help with emissions.

0 Ohm R35 is available to provide a disconnect from 12V generated by the Flyback and from the rest of the system that is powered by the 12V flyback winding.

Load simulations can be accomplished by not populating R35 and by populating R36 with the appropriate load resistance.

0 Ohm R47 is available to provide a disconnect from 5V generated by the Flyback and from the rest of the system that is powered by the 5V flyback auxilliary winding. This will not disconnect the 5V from the feedback for the flyback controller.

Load simulations can be accomplished by not populating R47 and by populating R49 with the appropriate load resistance.

C63 can be a 50V capacitor but 100V was chosen to reduce the amount of BOM line items.

C54 can be a 50V capacitor but 100V was chosen to reduce the amount of BOM line items.

R34 dissipates power linked to leakage energy and C54 ensures low-voltage ripple.

C67 only needs a 16V rating but due to BOM simplicity a 25V cap was chosen.

C62 can be a 16V cap but there are no 15 pF capacitors rated at less than 50V in current Altium libraries.

RC snubbers on D7 and D8 can be used to dampen parasitic oscillations. High frequency ringing can be due to parasitic inductance of the transformer and parasitic capacitance of the diode.

Test points across R45 are used to measure current

D4 should not be installed in between the transceiver and choke unless inductive flyback transients occur from common-mode choke.

TVS diodes should, in a typical scenario, be installed closest to the connector as displayed by D5.

60.4 Ohm CAN Split resistors need to be rated for possible short on 12V Battery. P = 12V^2 / 120.8 Ohm = 1.2 W

System requirements will determine bias capacitors on digital isolator. The device will work in many applications with only a 0.1 uF capacitor on VCC1 and VCC2.

RC snubber: DNP. Could be used to modify slew rate of the gates.

Nominal Input: 48VEnabled, Max: 1.7 mAEnabled, Typ: 1.4 mA

Power, Max: 81.6 mWPower, Typ: 67.2 mW

48V_BATT_B and 48V_FILTERED_B rails need to withstand a maximum voltage of 70V (per LV148). Therefore, the summation of caps in series could equal 87.5V by applying a 25% margin on 70V max voltage.

Series capacitors voltage ratings were selected to reduce the amount of BOM line items.

Due to the max current of 30A and worst case Rds(on) of a single FET the power dissipation would cause the temperature rise to be too significant. By adding a FET in parallel, the Rds(on) will be cut in half which will reduce the power dissipation and, in turn, reduce the temperature rise.

Pin FSW is tied low to put switching frequency at 2.5 MHz. Output voltage is fixed at 3.3V

therefore FB pin is tied to GND plane to improve thermal performance.

Peak Output Current = I_limf + (Vin-Vout) / L x tpd

Peak Output Current is approximately 2.4A

I_limf max = 2.2AVin_max = 17V Vout = 3.3VL = 2.2uHtpd = 30ns

Inductor Ripple Current Max = Vout x ( (1-Vout / Vinmax) / (Lmin x fsw) )

Peak Ripple Current is approximately 0.5A

Vout = 3.3 VVinmax = 17 VLmin = 2.2 uHfsw = 2.5 MHz

Inductor Current Max = Iout_max + Inductor Ripple Current Max / 2

Inductor Current Max is approximately 2.65 A

One 10 uF input Capacitor is recommended. However, additional capacitance can be added to reduce input current ripple further.

Only 25V caps are needed but 50V was chosen to reduce the amount of BOM line items.

Recommended to place a capacitor of 0.1 uF from AVIN to AGND to avoid potential noise coupling.

Input Voltage: 12VQuiescent Current, Max: 25 uAQuiescent Current, Typ: 17 uA

Device Power, Max: 0.3 mWDevice Power, Typ: 0.204 mW

One output capacitor is recommended but an additional can be added to help with load transients.

R12 doesn't need to be a 1% resistor but it was chosen to reduce BOM line items.

To disable Buck converter DNP R12 and deliver an external signal via EN_3V3 or short across 12V_B and EN_3V3.

10 Ohm Resistors, 1.5 uF capacitors and 22uF capacitor provide differential mode filtering on current sense measurement.

PWM Switching Frequency can range from 15 kHz to 50 kHz

Gate Resistor can be modified to control the FET time. Diode in parallel will help improve FET off time.

The RCD clamps across each FET will clamp the positive ringing Drain to Source and avoid the FET being pushed in Avalanche condition. The RC circuit values will require tuning.

TVS on gate to source will protect the FETs gate.

Supply Voltage: 12 VOperating Current Max: 5.5 mA

Power for all 3 phases: 198 mW
