LM5034MTC

DC DC Switching Controllers Overview

The LM5034MTC is a dual interleaved active clamp current mode controller designed for high-voltage forward converter topologies. It integrates P-channel clamp FETs and supports switching frequencies of 200 kHz or 600 kHz. The device operates with a supply voltage range of 13 V to 100 V and delivers up to 2.5 A output current. It features a maximum duty cycle of 76% and provides two isolated outputs. The component functions within a junction temperature range of -40°C to +125°C and is housed in a 20-TSSOP package.

DC DC Switching Controllers Feature Summary

• Integrates P-channel clamp FETs for active clamp operation
• Supports dual interleaved control for reduced ripple
• Enables clock synchronization for frequency alignment
• Includes soft-start functionality for controlled ramp-up

DC DC Switching Controllers Applications

• High-voltage DC-DC conversion systems
• Isolated power supplies with forward topology
• Industrial equipment requiring dual isolated outputs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., MTC vs. MTCX) against the required packaging format, as tape-and-reel variants may differ from tube packaging. Confirm RoHS compliance status through official datasheets. Check for obsolescence notices, as some variants may be marked as not recommended for new designs. Ensure the operating temperature range meets system requirements before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high input voltages up to 100 V and precise current mode control. The integrated P-channel FETs simplify the design by reducing external component count compared to N-channel alternatives. Consider the available switching frequency options (200 kHz or 600 kHz) when determining transformer size and efficiency targets. Verify that the 20-TSSOP package fits the thermal and spatial constraints of the target PCB layout.

DC DC Switching Controllers Part Context

The LM5034 belongs to Texas Instruments' family of high-voltage switch controllers optimized for forward converters. It addresses the need for efficient active clamp recovery in high-voltage environments. The device combines control logic with power stage drivers to streamline the design of robust, isolated power solutions for industrial and commercial applications.
