LT8390IUFD#TRPBF

LT8390IUFD#TRPBF is an Analog Devices/Linear Technology part: LT8390 is a high‑efficiency, wide‑input‑range dc–dc switching regulator controller intended for buck/boost/buck‑boost topologies. It typically drives external MOSFETs to build compact, efficient power converters, suitable for automotive and industrial applications. The suffix IUFD denotes the Pb‑free package variant; #TRPBF indicates Tape & Reel Pb‑free packaging. Features commonly include current‑mode control, programmable switching frequency, cycle‑by‑cycle current limit, undervoltage/overvoltage protection, thermal shutdown, and status/fault outputs. It supports flexible topologies with good efficiency and moderate external components. For exact electrical specs, pinout, recommended circuits, and package details, consult the LT8390 datasheet and Analog Devices product notes.

Here are typical features of the LT8390IUFD#TRPBF (datasheet-based; exact specs may vary by variant):
- Wide input voltage range (about 6–60 V) for automotive/industrial use
- Synchronous buck/boost/buck-boost operation with integrated MOSFETs (4-switch topology)
- Current-mode control with slope compensation
- Programmable switching frequency (up to several hundred kHz)
- Flexible regulation with feedback options (multi-mode/independent or single feedback)
- Enable/disable control and soft-start
- Protections: undervoltage lockout, overvoltage protection, overcurrent/short-circuit protection (cycle-by-cycle), and thermal shutdown
- High efficiency from synchronous rectification
- Robust start-up and deep-discharge behavior suitable for automotive/industrial environments
- Pb-free, tape-and-reel packaging (TRPBF) for automated manufacturing
- Industrial temperature range option (I variant)
Note: Confirm exact features and pins from the specific datasheet revision for LT8390IUFD#TRPBF, as packaging and parameter values can vary by lot.

- Pin count: 28 pins (28‑pin package, LT8390IUFD#TRPBF).
- Function: A 4‑switch synchronous buck/boost controller. It drives two high‑side and two low‑side external MOSFETs to regulate a wide input voltage to a controlled output, using PWM/current‑mode control with soft‑start, feedback, enable, and protection features (UVLO/OV/OC/OT). Suitable for automotive and other wide‑input applications.

- Manufacturer: Analog Devices, Inc. (ADI). The LT8390 originated from Linear Technology and ADI acquired Linear Technology in 2017, so the current maker is Analog Devices.
- What kind of company: A U.S.-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

LT8390IUFD#TRPBF is a wide-input buck-boost DC-DC controller. Typical application areas:
- Universal-input automotive and industrial power supplies (buck/boost regulation)
- Battery-powered and portable devices with varying input voltages
- LED lighting drivers (constant-current/constant-voltage)
- Solar energy systems and standalone battery charging regulators
- Telecommunication, instrumentation, and auxiliary power rails requiring compact, high-efficiency regulators
