Description
LTC3310SIV#WPBF is a high-efficiency synchronous buck–boost DC‑DC converter from Analog Devices (formerly Linear Technology). It regulates a supplied voltage over a wide input range to a programmable output, bucking or boosting as needed to maintain the target rail.
Key points:
- Features: integrated high‑side and low‑side MOSFETs, current‑mode control, programmable switching frequency, adjustable output via feedback network, soft‑start, and protections (overcurrent, thermal shutdown, undervoltage lockout); includes a Power Good signal.
- Packaging/ordering: SIV denotes the device package variant; #WPBF identifies the packaging/lot code (lead‑free/RoHS-compliant, tape-and-reel option).
- Applications: ideal for battery-powered and portable electronics, energy harvesting, and any system requiring stable rails from a variable input.
- How to use: requires external inductor, input and output capacitors, and a feedback divider. Pinout and exact electrical specs are in the datasheet.
For precise specs, pinout, and application notes, consult the LTC3310SIV#WPBF datasheet.
