Product details

Overview

SIC464EVB-B from Vishay Siliconix is a reference evaluation board designed to demonstrate and validate the SiC464 2 A synchronous buck DC/DC converter in its PowerPAK® MLP55-27L package. It supports 4.5 V to 60 V input, delivers adjustable output down to 0.8 V, operates up to 2 MHz, and enables fast transient response with ceramic output capacitors - ideal for industrial power supplies, robotics, and battery-powered embedded systems.

For engineers reviewing the SIC464EVB-B datasheet, SIC464EVB-B pinout, SIC464EVB-B application, or SIC464EVB-B equivalent, this board provides verified layout, thermal performance, protection behavior (OCP/OVP/UVP/OTP), and configuration flexibility for SiC464-based designs - including soft-start tuning, frequency selection, current limit adjustment, and ultrasonic mode validation.

Technical Context

The SIC464EVB-B implements the SiC464 microBUCK® regulator in voltage-mode constant-on-time (COT) control with adaptive zero-current detection. It validates the full functional chain: VCIN/VIN decoupling, BOOT capacitor/resistor network, PHASE/SW node routing, AGND/PGND separation, and VSNS-based ripple injection for stability with low-ESR ceramics.

It supports all SiC464 operational modes - forced CCM, power-save, and ultrasonic - via MODE and ULTRASONIC jumpers, and enables real-world verification of key behaviors: pre-bias start-up, output voltage tracking, PGOOD timing (15–35 μs delay), and valley-current OCP set by R_ILIM (3.2–4.8 A typical).

FAQ

What is the primary purpose of the SIC464EVB-B evaluation board?

The SIC464EVB-B is a reference design board built to evaluate the SiC464 2 A synchronous buck regulator. It provides a fully laid-out, tested PCB with optimized power delivery, thermal management, and signal integrity - enabling engineers to validate performance, configure operating modes (frequency, soft start, current limit), and verify protection features before integrating the SiC464 into their own systems. The SIC464EVB-B directly supports design-in of the SIC464ED-T1-GE3 device.

Does the SIC464EVB-B support all SiC464 operating modes?

Yes, the SIC464EVB-B supports forced continuous conduction mode (CCM), power-save mode, and ultrasonic mode via configurable jumpers on the MODE and ULTRASONIC pins. These allow real-world validation of diode emulation, frequency foldback, and audible-noise suppression - all documented in the SiC464 datasheet. The SIC464EVB-B's layout and component selection ensure stable operation across all three modes without modification.

Can the SIC464EVB-B be used to test output voltage sequencing or tracking?

Yes, the SIC464EVB-B supports output voltage tracking and sequencing with pre-bias start-up as specified for the SiC464. Its VFB and SS circuitry allows connection to external tracking controllers or master supplies, and the EN pin enables precise power-up/down coordination. This capability is confirmed in the SiC464 datasheet and validated on the SIC464EVB-B through functional testing under pre-biased load conditions.

What protection features are demonstrated on the SIC464EVB-B?

The SIC464EVB-B demonstrates full SiC464 protection: over-current (valley-current OCP), output overvoltage (OVP), output undervoltage/short-circuit (UVP with auto-retry), over-temperature (OTP with 35 °C hysteresis), and input UVLO. Each is implemented per datasheet thresholds - e.g., OVP triggers at +20% above 0.8 V reference, and OTP trips at 150 °C. The SIC464EVB-B includes test points and observable waveforms to verify these responses.

Is Vishay PowerCAD simulation support available for designs based on the SIC464EVB-B?

Yes, Vishay PowerCAD online design simulation tool fully supports the SiC464 - the core device on the SIC464EVB-B. Engineers can import SIC464EVB-B component values (R_fSW, R_ILIM, R_FB, C_SS, VRAMP network) into PowerCAD to simulate efficiency, loop stability, transient response, and thermal performance. This integration ensures correlation between SIC464EVB-B measurements and simulation results for production design handoff.
