LT3782EFE

LT3782EFE is a dual, interleaved, current‑mode step‑down controller from Analog Devices (Linear Technology). It drives two external N‑channel MOSFETs to form a two‑phase buck regulator, enabling high‑current, low‑noise outputs. Key features: wide input range, independently sensed current per phase, programmable oscillator frequency, programmable soft‑start and current limit, overvoltage and thermal protection, and enable/shutdown capability. Designed for high‑current power rails (CPU/GPU cores, telecom). The EFE suffix denotes RoHS‑compliant, lead‑free packaging and extended temperature performance. For exact electrical specs and pinout, consult the LT3782 data sheet and packaging details.

Here are typical features of the LT3782EFE family (high-level, consult datasheet for exact numbers):
- High-voltage buck-boost DC-DC regulator with integrated MOSFETs (synchronous rectification) for high efficiency.
- Wide input voltage range suitable for automotive/industrial applications.
- Buck, boost, and buck-boost operation to regulate outputs above or below Vin.
- Current-mode control with cycle-by-cycle current limiting.
- Programmable output voltage via feedback network; adjustable enable/shutdown.
- Soft-start to limit inrush; fault handling and protection features.
- Overcurrent/short-circuit protection, overvoltage protection, and thermal shutdown.
- Switching-frequency programming and/or external synchronization options.
- Optional fault/status outputs for system monitoring.
- RoHS-compliant package (suffix EFE); available in compact MSOP/TSSOP-like formats.
Note: precise electrical specs (Vin range, Vout range, current limit, switching frequency, protection behavior) vary by variant. For exact figures, refer to the LT3782EFE datasheet.

- Pin count: 16 pins (LTC/LT suffix devices with EFE package are 16-pin).
- Function: High-voltage, current‑mode switching regulator controller (buck/boost topology) for LED driver applications, typically driving external MOSFETs with current regulation.

Analog Devices, Inc. (ADI) is the manufacturer. The LT prefix originally came from Linear Technology, which was acquired by Analog Devices in 2017. Analog Devices is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for industrial, automotive, communications, and consumer markets.

LT3782EFE is a high-efficiency constant‑current LED driver suitable for wide-input buck/boost topologies. Typical applications:
- Automotive and industrial lighting (headlamps, taillamps, interior/exterior)
- LED signage and backlighting
- Street/area/high‑bay lighting
- Solar/off‑grid LED lighting
- Any high‑power LED application requiring wide input range and reliable current regulation.

LT3782EFE comes in a 20‑pin TSSOP package with an exposed pad (EP).
