LT8648SEV#PBF

LT8648SEV#PBF is Analog Devices’ Pb-free evaluation board (EVM) for the LT8648 buck-boost DC-DC regulator. It provides a ready-to-run platform to evaluate the LT8648’s wide-input, high-efficiency DC-DC conversion for automotive and industrial applications.
What it includes:
- LT8648 on board with standard feedback network
- Input and output terminals, enable/mode control, current-sense/monitoring, protection features
- Test points for measuring efficiency, ripple, and transient response
- Factory-default component values, with easy customization of Vout via the feedback network
How to use:
- Connect a suitable Vin, apply a load, enable the device
- Adjust the feedback network to your target output
- Measure efficiency, regulation, transient response, and thermal performance

Note: PBF indicates Pb-free version of the evaluation board.

LT8648SEV#PBF is a wide-input buck-boost regulator with integrated FETs in a QFN package. There isn’t a direct one-to-one cross reference. Closest substitutes are other vendors’ wide-range buck–boost regulators with similar current/voltage specs. For exact equivalents, please share your required input range, output voltage/current, efficiency, and package constraints; I can suggest specific part numbers from TI, Analog Devices, ST, or Onsemi.

Here are the key features of the LT8648SEV#PBF evaluation board:
