概述

Description

LTC1923EGN#PBF is Linear Technology (now Analog Devices) part LTC1923—a DC-DC switching regulator. It is the Pb-free, 8-pin package (EGN) version used to regulate a higher input voltage down to a stable output by driving external power MOSFETs/inductor (i.e., a buck converter topology). The device is a controller with features such as fixed switching frequency, enable/disable control, protection (overcurrent/thermal), soft-start, and an adjustable output via feedback resistors.
Key points:
- Pb-free package: #PBF denotes lead-free.
- EGN: package code for the 8-pin device.
- Requires external components (inductor, diode or synchronous FETs) to complete the buck converter.
- Intended for portable, automotive, and other power-supply applications needing efficient voltage regulation.
For exact electrical specs, pinout, and application circuits, see the LTC1923 datasheet on Analog Devices/DigiKey.

Features

I don’t have the datasheet loaded here, but LTC1923EGN#PBF is a Linear Technology DC-DC controller. Typical official features you’d expect:
- External N-channel MOSFET driver for a high‑efficiency switching regulator
- Wide input voltage range suitable for automotive/industrial use
- Fixed-frequency, current‑mode PWM control
- Soft-start to limit inrush
- Enable pin and proper undervoltage lockout
- Overcurrent/short‑circuit protection (current limit)
- Thermal shutdown protection
- Feedback/voltage‑setting via external resistor network (adjustable output)
- Optional synchronization or frequency select (depending on variant)
- RoHS/lead-free package (PBF) in an 8‑pin package (EGN)
For exact voltage ranges, timing, protection thresholds, and pinout, please check the LTC1923 datasheet.

Package

Package: 8‑lead MSOP (Plastic Small‑Outline Package); Pb‑free/RoHS compliant.

Pinout

- Pin count: 8 pins (MSOP-8, as in LTC1923EGN#PBF).
- Function: A high-efficiency switching regulator controller (buck) that drives an external N-channel MOSFET to regulate a DC output. It provides current‑mode PWM control, soft-start, enable/UVLO, overcurrent protection, and a frequency set input (RT/CT). The power MOSFET and inductor are external.

Manufacturer

Manufacturer: Analog Devices, Inc. (the Linear Technology brand).
What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (Linear Technology was acquired by Analog Devices in 2017).

Application

Application areas of LTC1923EGN#PBF:
- Automotive power supplies and in-vehicle electronics
- Industrial equipment and factory automation power management
- Battery-powered portable devices requiring high-efficiency DC-DC conversion
- Distributed power architectures and point-of-load regulation
- Telecommunications and networking equipment DC-DC conversion
- General-purpose, high-efficiency power management in consumer electronics and instrumentation

Equivalent

Direct one-for-one equivalents for LTC1923EGN#PBF aren’t published; cross-refs vary by distributor. For precise substitutes, share Vin, Vout, Iout, and switching frequency, or allow me to fetch DigiKey/Mouser cross-refs. Functionally, you can consider Analog Devices LTC buck controllers in the same family (LTC19xx) or comparable TI/Renesas high-voltage buck controllers with similar specs, noting potential pinout/feature differences.
