SiC431, SiC437, SiC438 Reference Board User’s Manu
Reference Board User’s ManualHigh Voltage Synchronous Buck Regulators: 3 V to 24 VSiC431 (24 A), SiC437 (12 A), SiC438 (8 A)DESCRIPTIONThe SiC431/437/438 is family of synchronous buck regulators with integrated high side and low side power MOSFETs. Its power stage is capable of supplying up to 24 A continuous current at 1 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 3 V to 24 V input rail to accommodate a variety of applications, including computing, consumer electronics,telecom, and industrial. SiC43x series employs a constant ON time control architecture that supports ultrafast transient response with minimum output capacitance and tight ripple regulation at very light load. The device is internally compensated and no external ESR network is required for loop stability purposes. The device also incorporates a power saving scheme that significantly increases light load efficiency. The regulator integrates a full protection feature set, including output over voltage protection (OVP), cycle by cycle over current protection (OCP) short circuit protection (SCP) and thermal shutdown (OTP). It also has UVLO and a user programmable soft start. The SiC43x series is available in lead (Pb)-free power enhanced MLP44-24L package in 4 mm x 4 mm dimension.FEATURES•Versatile- Single supply operation from 3 V to 24 V input voltage -Adjustable output voltage down to 0.6 V - Scalable solution8 A (SiC438), 12 A (SiC437), 24 A (SiC431)- Output voltage tracking and sequencing with pre-bias start up- ± 1 % output voltage accuracy at -40 °C to +125 °C •Highly efficient - 97 % peak efficiency- 1 μA supply current at shutdown - 50 μA operating current not switching •Highly configurable-Four programmable switching frequencies available:300 kHz, 500 kHz, 750 kHz, and 1 MHz - Adjustable soft start and adjustable current limit - 3 modes of operation: forced continuous conduction,power save, or ultrasonic •Robust and reliable- Cycle-by-cycle current limit - Output overvoltage protection- Output undervoltage / short circuit protection with auto retry - Power good flag and over temperature protection •Design tools- Supported by Vishay PowerCAD Online Design Simulation (/power-ics/powercad-list/)- Design support kit (/ppg?74589)•Material categorization: for definitions of compliance please see /doc?99912APPLICATIONS•Industrial and automation •Home automation•Industrial and server computing•Networking, telecom, and base station power supplies •Wall transformer regulation •Robotics•High end hobby electronics: remote control cars, planes,and drones•Battery management systems •Power tools•Vending, ATM, and slot machinesORDERING TABLEPART NUMBER MODEOUTPUT CURRENTSiC431AEVB-A Ultrasonic24 A SiC431BEVB-APower safe 24 ASiC437AEVB-BUltrasonic 12 A SiC437BEVB-BPower safe12 A SiC438AEVB-B Ultrasonic 8 A SiC438BEVB-BPower safe8 ASPECIFICATIONSThis reference board allows the end user to evaluate the SiC43x series microBUCK® regulators for their features and functionalities. The user may also change the operating range may be modified by making changes to the jumper connections. See section “Selection Jumpers” below in the document.CONNECTION AND SIGNAL / TEST POINTS Power Terminals (J10)- +V IN (pin 1), V IN GND (pin 2)Connect to a voltage source to this pin. The minimum input voltage will be 3 V. For input voltages (V IN) below 4.5 V an external V DD and V DRD is required.- +V OUT (pins 5 and 6), V OUT GND (pins 3 and 4)Fig. 1 - SiC43x EVBSELECTION JUMPERSMode SelectJ1, to J8 and J15: there are 4 jumpers which allow the user to select one of four modes of operation.J1 to J4 to select switching frequency: 300 kHz to 1 MHz. Short pins 1 and 2 for PSM mode, short pins 2 and 3 for FCCM modeJ5 to J8 to select over current trip (I LIM). Short pins 1 and 3 to select 6 mS soft start, short pins 2 and 3 to select 6 mS soft startJ15 to select output voltage: 1 V, 3.3 V, 5 V and 12 V EnableJ9: this is the jumper that enables/disables the part.With J9 left open, the device is enabled, via R9 to V IN+. To disable the part, short J9.SIGNALS AND TEST LEADSInput Voltage SenseV IN_SENSE (TP11), GND IN_SENSE (TP12): this allows the user to measure the voltage directly at the input of the regulator bypassing any losses generated by connections to the board. These test points can also be as a remote sense port of a power source with remote sense capability.Output Voltage SenseV OUT_SENSE (TP13), GND OUT_SENSE (TP14): this allows the user to measure the output voltage directly at the sense point of the regulator bypassing any losses generated by connections to the board. These test points can also be as a remote sense port of an external load with remote sense capability.Power Good IndicatorPGD (J17): is an open drain output and is pulled up with a 100 kΩ resistor, R12, to V DD1 (≈ 5 V). When FB or V OUT are within -10 % to +20 % of the set voltage this pin will go HI to indicate the output is okay. To prevent false triggering during transient events, the P GOOD has a 25 μS blanking time.Power Up ProcedureBefore turning on the reference board, the user needs to select one of the three modes by shorting one jumper (see section on mode selection). It is recommend to disable theSiC431 before making any changes to the jumpers.SCHEMATIC FOR SiC431SCHEMATIC FOR SiC437, SiC438SCHEMATIC, DESIGN, BILL OF MATERIALS, AND GERBER FILES FOR PCB FABRICATIONThese files are as follows:•“*.DSN” for schematic design file•“*.DBK” for data backup file for Orcad•“.opj” Orcad project file.
