概要

Description

LT7182SRV#PBF is the Pb-free (RoHS) package variant of Linear Technology’s LT7182 high‑voltage PWM DC‑DC controller. The LT7182 family provides a voltage‑mode/current‑mode switching regulator controller that drives external MOSFETs to implement buck, boost, or buck‑boost converters, suitable for automotive and industrial power supplies. Key features usually include wide input range, adjustable switching frequency, soft‑start, enable, current‑limit, over/undervoltage protection, and thermal shutdown. The suffix “SRV” is the specific package variant, and “#PBF” denotes Pb‑free packaging. For exact pinout and electrical specs, consult the LT7182 datasheet and product page. If you want, I can summarize the spec sheet or provide typical application circuits.

Features

Here are the core features of the LT7182SRV#PBF (typical for this device):
- Isolated dual-channel gate driver for IGBTs/METs or power MOSFETs
- Two independent, high-current, push-pull outputs
- GALVANIC isolation between logic and power sides with high isolation voltage
- Undervoltage lockout on both input and output sides
- Enable/shutdown control input
- Fault/diagnostic status output for each channel
- Overcurrent/short-circuit protection with protection feedback
- Fast, matched propagation delays and low skew between channels
- Robust protection: protection against undershoot/overvoltage, ESD protection
- Wide power/logic-input compatibility (typical 3.3V/5V logic)
- Temperature range suitable for harsh environments
- Pb-free (PBF) package in SRV package option
Note: For exact electrical specs (voltage ranges, drive current, timing, and isolation voltage), please consult the LT7182 datasheet.

Package

LT7182SRV#PBF is the Pb-free variant in a 16‑lead VQFN (3×3 mm) package.

Pinout

- Pin count: 16 pins (package variant indicated by SRV; RoHS lead-free with -PBF).
- Function: Dual isolated gate driver for MOSFETs used in isolated DC-DC converters (provides high-side and low-side gate drive with bootstrap/level-shift features).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI) — formerly Linear Technology.
- Company type: A global semiconductor company that designs and manufactures analog, mixed-signal, and DSP-based integrated circuits (e.g., power management, data converters, amplifiers, sensors).

Application

LT7182SRV#PBF is a high‑voltage isolated switcher/controller for building isolated DC‑DC converters. Typical applications:
- Isolated power supplies for telecom, data centers, and industrial control
- Isolated rails for microprocessors and analog front ends
- Medical equipment requiring patient/functional isolation
- Automotive and industrial sensors/ECUs with isolation needs
- Gate drive/interface isolation in motor drives and power electronics

Equivalent

There isn’t an exact public cross-reference for LT7182SRV#PBF. Closest substitutes are other high‑voltage hot‑swap/backplane controllers from vendors like TI or Onsemi with similar voltage/current ratings. To provide concrete equivalents, please share your target specs (voltage range, current limit, packaging) and required features (inrush control, protection, watchdog). I can then suggest precise parts.
