概要

Description

LTC3114IFE-1#PBF is the Pb-free variant of Analog Devices/Linear Technology’s LTC3114. It’s a high-efficiency DC-DC switching regulator device used to convert a wide range of input voltages to a stable output in automotive, industrial, and battery-powered applications.
Key points
- Type: Highly integrated switching regulator (used as a buck/step-down converter in typical configurations).
- Features: Wide input range, high efficiency, external feedback for adjustable output, and built-in protection (overcurrent/thermal, etc.). Requires external components per the data sheet (inductors, capacitors, feedback resistors, etc.).
- Packaging: IFE denotes the specific package type; PBF indicates Pb-free (lead-free) packaging.
- Typical use: Power conversion from supply rails to a regulated output for core logic, peripherals, or battery-management circuits.
For exact electrical specs, pinout, and application guidance, refer to the LTC3114 data sheet and the product page for the IFE-1#PBF variant.

Features

Here are the key features of LTC3114IFE-1#PBF (high‑voltage buck/boost controller, Pb‑free):
- Wide input voltage range suitable for buck/boost operation (up to a high Vin, typically 60V class)
- Buck-boost controller requiring external MOSFETs (no internal power FETs)
- Current‑mode, fixed‑frequency PWM with cycle‑by‑cycle current limit
- Optional synchronization to an external clock
- Adjustable output via feedback network; supports various output voltages
- Enable/Shutdown and soft‑start for controlled startup
- Protections: overcurrent/short‑circuit, overvoltage, undervoltage, and thermal protection
- Fault reporting/status pins for monitoring
- Suitable for high‑efficiency, compact power‑path designs with external FETs
- Pb‑free, RoHS‑compliant package (PBF), device code LTC3114IFE‑1
Note: Exact electrical specs (Vin range, output current, efficiency, timing, and pinout) are in the datasheet for precise design values.

Package

Pb-free 16-pin QFN package (3×3 mm) for the LTC3114IFE-1#PBF.

Pinout

- Pin count: 20 pins (in the IFE package variant).
- Function: High‑voltage, bidirectional buck/boost DC‑DC controller with integrated power MOSFETs, used to regulate output voltage from a wide input range (battery/automotive applications) with PWM control, current limit, protections, and soft‑start.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LTC3114IFE-1#PBF is a Linear Technology part now under ADI after its acquisition.
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.
