Overview
Description
The LTC3310SEV#PBF is Analog Devices’ System Evaluation Board for the LTC3310 buck‑boost DC‑DC controller. It is a pre‑built demo board that lets you quickly evaluate the LTC3310’s performance in buck, boost, and buck‑boost operation over a wide input range with an adjustable output. The board includes the required external MOSFETs, inductor, sense resistor, feedback network, and test headers, so you can measure input/output, efficiency, current limit, and protection features with standard lab gear. The #PBF suffix denotes a Pb‑free (Pb‑free) version, while SEV indicates System Evaluation Board. To use it, connect an input supply to IN, connect your load to OUT, set the mode and output via the on‑board network/jumpers, and monitor signals at the provided test points. For complete details (pinout, wiring, BOM, and schematics) see the LTC3310 data sheet and the LTC3310SEV user guide on the Analog Devices website.
Features
LTC3310SEV#PBF is Analog Devices’ evaluation board for the LTC3310. Key features (concise):
- Demonstrates a dual-channel, synchronous buck/boost regulator (interleaved control) for high efficiency.
- Two adjustable outputs via resistor networks.
- Wide input voltage range and flexible layout for easy bench testing.
- Protection: current-limit/overcurrent protection and thermal protection.
- Soft-start, enable control, and fault/status indicators.
- Remote sense/feedback access with user-test points and hook-up headers.
- On-board sense resistors and output/input components; easy modification for experimentation.
- Pb-free (PBF) version; RoHS compliant.
- Documentation and reference designs available from Analog Devices.
Note: For exact electrical specs (voltages, currents, timing, and recommended components), refer to the LTC3310SEV#PBF datasheet and user guide.
