Overview
The LT3999IDD#TRPBF is a push-pull DC-DC switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 36V and provides a single adjustable output capable of delivering up to 1A of current. The device utilizes a push-pull topology suitable for isolated or non-isolated applications. It features a switch frequency range from 50kHz to 1MHz and is housed in a 10-WFDFN package with an exposed pad, designed for surface mount installation.
Feature Summary
- Push-pull transformer driver topology for isolated and non-isolated power conversion
- Adjustable output voltage configuration with 1A continuous current capability
- Wide input voltage operating range supporting diverse supply sources
- Frequency programmability allowing optimization for efficiency and component size
Applications
- Isolated DC-DC converter designs
- Non-isolated buck/boost power supplies
- Industrial control system power regulation
- Telecommunications equipment power stages
Procurement Notes
Verify the specific suffix IDD against official Analog Devices documentation to confirm pinout and thermal pad specifications. Ensure the TRPBF designation matches the required tape and reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and authenticity before finalizing procurement orders.
Selection Notes
Select this component when a push-pull topology is required for driving external transformers in isolated or non-isolated configurations. Consider the 1A output current limit and 36V maximum input voltage constraints during circuit design. Evaluate the need for frequency programming within the 50kHz to 1MHz range to meet electromagnetic interference requirements and passive component size limitations.
Part Context
This part belongs to the LT3999 series of push-pull DC/DC drivers from Analog Devices. The series is characterized by its ability to drive external switches for various power conversion topologies. The IDD variant specifies the particular package type and temperature rating, distinguishing it from other suffixes in the same functional family.
Replacement Considerations
LT3999EDD#TRPBF is a confirmed substitute within the same series offering identical functionality but potentially differing in package or thermal characteristics.
