Where the TPS560430XDBVR fits

Typical applications

  • Point‑of‑load regulation on industrial control boards
  • Factory automation modules and distributed power rails
  • Consumer electronics power rails (audio, set‑top boxes, appliances)
  • Battery‑powered equipment with stringent standby requirements
  • Embedded and IoT systems, gateways, and sensor hubs

Who should consider this device?

  • Hardware engineers seeking a compact, easy‑to‑route buck regulator for up to 600 mA loads

  • Sourcing managers standardizing on SIMPLE SWITCHER devices to streamline qualification

Feature details and design value

Wide input capability up to 36 V

With a maximum input voltage rating of 36 V, the Texas Instruments TPS560430XDBVR can be deployed behind 12 V and 24 V industrial supplies, vehicle accessory rails, and other unregulated sources that may experience line excursions. This simplifies front‑end protection strategies and broadens reuse across platforms that share common mechanicals but differ in supply characteristics.

High‑efficiency sleep mode for light loads

Light‑load power loss often dominates modern designs, particularly in always‑on embedded or IoT equipment. The TPS560430XDBVR includes a sleep mode that improves light‑load efficiency, helping reduce average power consumption and thermal rise in standby or low‑duty applications.

Compact SOT‑23‑6 (DBV) package

The SOT‑23‑6 (DBV) package makes the regulator well‑suited to dense layouts, small sensor boards, and space‑constrained end products. Its six‑pin footprint supports straightforward routing for VIN, ground, control, and switch node connectivity while conserving board space compared to larger packages.

Enable/Shutdown for sequencing and power savings

An enable/shutdown function allows simple power domain control. Designers can sequence start‑up, implement system sleep states, or gate power to subsystems, improving overall energy efficiency without additional control ICs.

Practical design considerations

  • Input voltage headroom: While the device accepts up to 36 V, allow margin for transients and derating in harsh environments. Front‑end protection (e.g., TVS, input filtering) may still be required depending on the use case.
  • Thermal planning: The −40°C to +125°C operating temperature range supports industrial environments. Actual temperature rise will depend on efficiency, load current, ambient conditions, copper area, and airflow. Use layout copper and vias to help spread heat from the switch node and ground.
  • Light‑load behavior: Sleep mode enhances efficiency at low currents. Validate load transients across operating modes to ensure downstream rails remain within regulation for your system’s duty cycles.
  • Enable control: Use the enable/shutdown input to reduce standby power when subsystems are idle or to coordinate start‑up among multiple rails.

Items such as switching frequency, soft‑start behavior, current limit method, compensation, and output voltage programming are Not specified in datasheet. Consult the TI datasheet for full electrical characteristics and design equations.

Application notes and layout hints

While exact internal operation details and recommended component values are Not specified in datasheet, the following general practices help achieve robust designs with compact buck converters:

  • Keep the high‑di/dt loop (input capacitor, switch pin, diode/low‑side path, and ground) as tight and short as possible.
  • Place the input bypass capacitor close to VIN and GND pins.
  • Route the feedback network away from the switch node; use a quiet ground reference.
  • Provide adequate copper for thermal spreading and low impedance ground return.
  • Validate stability and transient performance across line, load, and temperature.
