概述

Description

LT1617ES5-1#TRMPBF is a Linear Technology/ Analog Devices part number for a fixed- or semi-fixed variant of the LT1617 buck switching regulator family. The suffixes indicate packaging and ordering details:
- ES5-1: the specific variant (output voltage, revision) within the LT1617 family.
- #TRMPBF: distributor packaging and Pb-free status (TR = Tape-and-Reel, MPBF = Pb-free).
General purpose:
- It’s a DC-DC step-down (buck) regulator intended to convert a higher input voltage to a lower, regulated output with external components (inductor, diode or switch, input/output capacitors, and a feedback network).
- Performance (input range, output current, efficiency, compensation) is defined in the exact datasheet for the LT1617 family and varies by variant.
What to do:
- Consult the LT1617 datasheet and the specific ES5-1 variant page for exact electrical specs, pinout, and application circuits.
- Use the datasheet’s recommended external components and typical application circuits to implement your design.

Features

LT1617ES5-1#TRMPBF is a Linear Technology buck regulator (Pb‑free, tape & reel). Key features typically include:
- Wide input voltage range and high efficiency switching regulator
- Adjustable output via external feedback resistors
- Internal switch with current‑mode control for fast transient response
- Fixed switching frequency with programmable on/off characteristics
- Enable/shutdown pin to disable regulator
- Soft‑start to minimize inrush and output overshoot
- Protection: overcurrent/short‑circuit and thermal shutdown
- Low quiescent current for good light‑load efficiency
- Small package option and RoHS compliant
Note: for exact electrical specs (voltage ranges, switching frequency, load/line regulations, and pinout), please refer to the official datasheet.

Package

It’s an 8-pin MSOP (3x3 mm) package. TRMPBF indicates Tape & Reel, Pb-free (lead-free).

Pinout

- Pin count: 5 pins (SOT-23-5 / ES5 package)
- Function: High-efficiency step-down DC-DC switching regulator (buck regulator) with an internal switch
- Pin functions (typical): VIN, GND, SW (switch node), FB (feedback), EN/SHDN (enable)

Manufacturer

Manufacturer: Linear Technology Corporation (LT), now part of Analog Devices.
What kind of company: A semiconductor company that designs and manufactures high-performance analog and mixed-signal integrated circuits, including power management ICs. Linear Technology was acquired by Analog Devices in 2017, and its products are marketed under the Analog Devices umbrella.

Application

LT1617ES5-1#TRMPBF is a high-efficiency buck DC-DC converter. Typical applications include:
- Portable/battery-powered equipment
- Point-of-load regulation for CPUs/FPGA/DSPs
- Automotive 12V to lower rails
- Telecom/networking power supplies
- Industrial control and instrumentation
- LED backlight/lighting driver supplies
Used wherever compact, efficient step-down power is needed.
