Overview

Description

LTC1778EGN#TRPBF is a Linear Technology (now Analog Devices) DC-DC switching regulator controller IC. It’s designed to drive external MOSFETs to implement a high-efficiency buck regulator. Typical features (as with LTC controllers) include current-mode control, adjustable switching frequency, soft-start, enable/shutdown, various protection functions (overcurrent, undervoltage, overvoltage), and sometimes clock synchronization for multi-phase designs. The EGN suffix indicates the Pb-free, RoHS-compliant 16-pin package, and TRPBF denotes Tape & Reel packaging (Pb-free).
Common uses include power supplies for CPUs, memory, other digital ICs, and telecom equipment. For exact electrical specs (input range, output current, switching frequency, pinout, protections), consult the LTC1778 datasheet and the packaging details from the supplier.

Features

Here are the typical features you’d expect for the LTC1778EGN#TRPBF family (check the exact datasheet for precise numbers):
- Wide input range and high efficiency
- Synchronous buck regulator with integrated MOSFETs
- Adjustable output via external feedback resistors
- Current-mode control for fast transient response
- Enable/shutdown and soft-start
- Protection: overcurrent/short-circuit, overvoltage, undervoltage lockout, thermal shutdown
- Power-good/status signaling
- Switching frequency: fixed or programmable; possible clock synchronization
- Mode options: PWM/PFM/auto modes for light-load efficiency
- Remote sense option and robust load regulation
- Packaging: RoHS-compliant, 20-pin TSSOP-like (EGN) package
- Tape-and-reel packaging: TRPBF variant
Note: Exact electrical specs (voltage range, output current, switching frequency, etc.) vary by revision and configuration. For precise figures, refer to the LTC1778 datasheet and the specific “EGN#TRPBF” variant document.

Package

The LTC1778EGN#TRPBF comes in a 20‑lead TSSOP package (Pb‑free) with Tape‑and‑Reel (TR) packaging.

Pinout

- Pin count: 8 pins (LTC1778EGN in an 8‑lead package, MSOP‑8).
- Function: DC‑DC switching regulator controller for a buck (step‑down) converter. It requires external MOSFETs, inductor, and feedback network to regulate output voltage.

Manufacturer

Analog Devices, Inc. (ADI). The LTC1778 was originally from Linear Technology; Linear Technology was acquired by Analog Devices in 2017, so ADI is the current manufacturer. ADI is a US-based multinational semiconductor company specializing in analog, mixed-signal, and digital signal processing ICs for power management, automotive, industrial, communications, and consumer markets.

Application

Typical application areas for LTC1778EGN#TRPBF (a high-efficiency DC-DC step-down regulator):
- Automotive and battery-powered systems
- Industrial automation and controllers
- Networking/telecom power supplies and POL rails
- Microprocessors, DSPs, FPGAs, ASICs require multiple low-voltage rails
- Portable/handheld devices and wearables
- Consumer electronics, LCD/AV equipment, set-top boxes needing efficient dc-dc conversion
Note: used for compact, high-efficiency voltage step-down applications.
