LM5041MTCX

DC DC Switching Controllers Overview

The LM5041MTCX is a cascaded PWM controller from Texas Instruments designed for push-pull power converter topologies. It supports both current-fed and voltage-fed configurations, including bridge converters. The device operates with a maximum switching frequency of 1 MHz and features a fixed maximum duty cycle of 50%. It delivers a peak output drive current of 1.5 A at a supply voltage of 16 V. The controller accepts an input voltage range between 15 V and 90 V, with a nominal rating of 48 V. It functions within an extended temperature range of -40°C to +125°C and is housed in a TSSOP-16 package.

DC DC Switching Controllers Feature Summary

• Supports implementation of current-fed or voltage-fed push-pull and bridge power converters
• Provides high-speed gate drive capability with 10 ns rise and fall times
• Features programmable output types for flexible control loop integration

DC DC Switching Controllers Applications

• High-frequency DC-DC conversion systems
• Industrial power supply designs requiring push-pull topology
• Server and telecom power architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-16 package marking matches the required board layout specifications. Ensure the operating voltage range aligns with the system's input requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing push-pull converters requiring up to 1 MHz switching frequencies. The 1.5 A output drive current suits direct driving of medium-power MOSFETs without external buffers. Consider the 50% duty cycle limit for transformer reset requirements in current-fed applications.

DC DC Switching Controllers Part Context

This part belongs to the LM5041 series of cascaded PWM controllers. It is distinct from voltage reference devices sharing similar numerical prefixes. The MTCX suffix denotes the surface-mount TSSOP-16 package configuration used for automated assembly processes.
