LT1618EDD#TRPBF

Overview

The LT1618EDD#TRPBF is a Constant-Current/Constant-Voltage Step-Up DC/DC Converter manufactured by Analog Devices Inc. It operates within an input voltage range of 1.6 V to 18 V and supports output voltages from 1.263 V to 36 V. The device features a fixed 1.4 MHz switching frequency and utilizes current-mode control with a 50 mV current sense threshold. It is housed in a 10-pin DFN package (3 mm x 3 mm) with an exposed thermal pad, designed for applications requiring precise current regulation.

Feature Summary

Integrates dual feedback loops for simultaneous constant-current and constant-voltage regulation
Supports wide input voltage ranges suitable for single-cell lithium-ion batteries
Enables compact designs through high-frequency operation allowing small passive components

Applications

LED backlight drivers
USB-powered boost or SEPIC converters
Input current-limited boost or SEPIC converters
Battery charger ICs

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc., formerly Linear Technology. Ensure the specific 10-pin DFN footprint matches the target PCB layout. Cross-reference the datasheet revision to confirm pinout consistency for integration.

Selection Notes

Select this component for applications requiring independent control of both load current and output voltage. The 1.4 MHz frequency minimizes external inductor size. Verify that the required output voltage remains within the 36 V maximum limit. Ensure the input source falls within the 1.6 V to 18 V operational window for proper regulation.

Part Context

This part belongs to the LT1618 family of step-up DC/DC converters. It shares functional characteristics with variants such as LT1618EDD and LT1618EMSPBF, differing primarily in packaging and reel configuration. The device is categorized under PMIC - Power Management ICs, specifically switching regulators.
