LTC3310SIV#WPBF

LTC3310SIV#WPBF is the orderable code for Analog Devices’ LTC3310 dual synchronous buck regulator in a Pb‑free WPBF (WSON‑8) package. Key points:
- What it is: A dual DC‑DC converter (two synchronous buck channels) that regulates two outputs from a higher input voltage.
- Package/variant: SIV denotes the device variant; WPBF is the WSON‑8 lead‑free package code.
- How it works: Each channel uses integrated high‑side FETs (synchronous rectification); external inductor, input capacitor, and feedback network set the outputs. Features typically include adjustable switching frequency, enable/soft‑start, current limit, undervoltage protection, and power‑good signaling.
- How to use: Select input range and per‑channel output targets via feedback resistors; follow recommended PCB layout and decoupling per the datasheet; add appropriate inductors, capacitors, and sense components.
- For specifics: Refer to the LTC3310 datasheet and application notes for exact electrical specs, pinout, and layout guidelines.
If you want, I can summarize the exact specs from the datasheet.

Pb-free 16‑lead QFN package (4×4 mm) with exposed pad. The #WPBF suffix denotes Pb-free QFN packaging.

- Pin count: 16 pins (16-pin package)
- Function: High-efficiency synchronous buck-boost DC-DC regulator (integrated MOSFETs) for converting an input source (e.g., battery) to a regulated output.

Manufacturer: Analog Devices (the LTC brand, formerly Linear Technology).
What kind of company: Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

Applications: battery-powered portable devices and wearables; IoT sensors and handheld instrumentation; energy-harvesting (solar) systems; automotive and industrial power management requiring buck/boost regulation from varying inputs; point-of-load regulation for DSPs, MCUs, radios and FPGAs; any system needing a high-efficiency buck-boost regulator from low input voltages to a stable output.
