LTC3119EUFD#TRPBF

Introduction to LTC3119EUFD#TRPBF
- What it is: A Linear Technology (now Analog Devices) DC-DC converter IC—the LTC3119—designed as a high-efficiency buck-boost regulator for battery-powered systems.
- Package/code: EUFD denotes the specific package variant; #TRPBF indicates Pb-free, Tape & Reel packaging.
- Key capability: Automatic buck/boost operation with integrated switching elements and control logic to regulate an output voltage from a wide range of inputs.
- Typical features: Programmable output, soft-start, enable/shutdown, protection (overcurrent/thermal), and good transient response.
- Applications: Portable electronics, battery management, automotive/industrial power rails, solar/battery hybrid systems.
- How to use: Choose feedback resistors to set Vout, follow datasheet layout guidelines, and reference the evaluation board for wiring and peripheral recommendations.
- For exact specs: consult the LTC3119 datasheet and application notes to confirm input range, load current, efficiency, and pinout for your design.

Here are the key features of LTC3119EUFD#TRPBF (from the datasheet):
- Synchronous buck-boost DC-DC converter with integrated MOSFETs
- Wide input-voltage range suitable for automotive and portable use
- Buck-boost operation: can regulate output above or below input
- Adjustable output via external resistor network
- Auto PWM/PFM mode for high efficiency across load range
- Soft-start to minimize inrush and output overshoot
- Current-limit protection with short-circuit protection
- Over/under voltage protection (UVLO/OVLO) and thermal shutdown
- Enable input and a status/power-good indication
- Low quiescent current for efficiency in light-load/battery apps
- Small 8-pin package (EUFD variant) with Tape-and-Reel (TRPBF) options
Note: exact pinout, voltage ranges, and programming details are in the official datasheet.

28-lead QFN (leadless) package, RoHS Pb-free (TRPBF).

- Pin count: 28 pins (QFN package, 5x6 mm typical for LTC3119EUFD#TRPBF).
- Function: High-efficiency buck-boost DC-DC converter with integrated switches and power-path management (can operate in buck, boost, or buck-boost mode) to regulate output voltage from inputs above or below the desired output, with built-in protections (current limit, OVP, etc.).

- Manufacturer: Analog Devices, Inc. (the LTC/Lin ear Technology part is now under Analog Devices, following their 2017 acquisition).
- Company type: A multinational semiconductor company specializing in analog, mixed-signal, and digital signal processing (DSP) integrated circuits.
