Texas Instruments TPS563210EVM-663

Overview

TPS563210EVM-663 from Texas Instruments is an evaluation module for the TPS563210 synchronous buck converter, configured to deliver 1.05 V at up to 3 A from a 4.5–17 V input. It implements D-CAP2™ adaptive on-time control, operates at 650 kHz nominal switching frequency, and features dedicated Power Good (PG) and soft-start (SS) pins for system sequencing and monitoring.

For engineers reviewing the TPS563210EVM-663 datasheet, TPS563210EVM-663 test setup, TPS563210EVM-663 efficiency curves, or TPS563210EVM-663 load transient response, this EVM provides validated reference design data-including measured output ripple (20 mV_PP at 12 V_IN/3 A), line/load regulation, startup/shutdown waveforms, and board-level layout guidance-for rapid prototyping of point-of-load DC/DC conversion in industrial and embedded power systems.

Technical Context

The TPS563210EVM-663 implements the TPS563210DDF IC in a fully assembled, tested PCB form factor with fixed 1.05 V output set by R1 = 3.74 kΩ and R2 = 10.0 kΩ. Its D-CAP2™ control architecture eliminates external compensation and enables fast transient response using low-ESR ceramic output capacitors (C5–C8 totaling 20–68 µF).

Key board-level features include VIN/VOUT terminal blocks (J1/J2), EN control via JP1 shunt, switch-node access (TP4), feedback loop test point (TP5), and dedicated PG/SS monitoring (TP3/TP7). The layout uses top-layer power routing, bottom-layer ground plane, and optimized placement of input decoupling (C1–C3) and output bulk capacitance (C6–C8).

FAQ

What is the primary function of the TPS563210EVM-663?

The TPS563210EVM-663 is a fully assembled evaluation module that demonstrates the operation and performance of the TPS563210 synchronous buck converter IC. It delivers 1.05 V at up to 3 A from a 4.5–17 V input and provides accessible test points, configurable enable control, and documented efficiency/ripple/transient measurements to support power design validation. Engineers use the TPS563210EVM-663 to verify system-level behavior before committing to custom PCB layout.

Can the output voltage of the TPS563210EVM-663 be adjusted?

Yes, the output voltage of the TPS563210EVM-663 can be adjusted by changing resistor R1, which forms part of the feedback divider network with R2 (10.0 kΩ). The TPS563210EVM-663 ships with R1 = 3.74 kΩ for 1.05 V, but Equation 1 in the User's Guide allows calculation of alternate R1 values for outputs from 0.765 V to 6.5 V. Standard resistor values for common voltages-including 1.2 V, 1.5 V, and 3.3 V-are listed in Table 3-1.

What test points are available on the TPS563210EVM-663 and what do they monitor?

The TPS563210EVM-663 provides eight labeled test points: TP1 (VIN positive), TP2 (GND reference), TP3 (EN signal), TP4 (switch node), TP5 (feedback loop injection), TP6 (VOUT positive), TP7 (VOUT GND), and TP8 (secondary GND). These allow direct oscilloscope probing of input/output voltage, enable timing, switching waveform, loop response, and ground integrity-enabling full characterization of the TPS563210EVM-663 under dynamic load and line conditions.

How does the TPS563210EVM-663 implement power sequencing and fault monitoring?

The TPS563210EVM-663 leverages the TPS563210 IC's dedicated Power Good (PG) and soft-start (SS) pins: PG asserts high when output voltage is within ±8% of regulation, enabling system-level power sequencing; SS controls ramp rate via external capacitor (not populated on EVM, but pin accessible at TP3). The jumper JP1 provides manual EN control-shunting EN to GND disables the converter, while connecting EN to VIN enables it-allowing safe startup and shutdown verification for the TPS563210EVM-663.

What is included in the TPS563210EVM-663 Bill of Materials (BOM)?

As documented in Table 6-1 of the User's Guide, the TPS563210EVM-663 BOM includes the TPS563210DDF IC in DDF package, 1.5 µH shielded inductor (Würth 744311150), six ceramic capacitors (0.1 µF, 10 µF, 22 µF variants), precision resistors (R1 = 3.74 kΩ, R2 = 10.0 kΩ), terminal blocks (J1/J2), shunts (SH-JP1/SH-JP2), and miniature test points (TP1–TP8). All components are surface-mount except J1/J2 and JP1/JP2, and manufacturer/part numbers are explicitly listed for traceability.
