LM3001M

AC DC Converters, Offline Switchers Overview

The LM3001M is a primary-side driver integrated circuit designed for use with the LM3101 secondary-side PWM controller in isolated DC-DC converter applications. It operates within an industrial temperature range of -40°C to +85°C and utilizes a BICMOS process technology. The device is housed in a 14-pin PDSO package with a 0.65mm pin pitch, featuring gull-wing terminals suitable for surface-mount assembly. It supports switching frequencies up to 1MHz and provides precision control for offline or other isolated converters through pulse communication with its companion controller.

AC DC Converters, Offline Switchers Feature Summary

Enables precise regulation of isolated DC-DC converters via pulse transformer communication
Operates as a primary-side driver paired with the LM3101 secondary-side controller
Supports fast loop response without introducing poles or zeros in the control loop

AC DC Converters, Offline Switchers Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the part number suffix matches the required package type and temperature grade. Confirm that the component is sourced from authorized distributors to guarantee authenticity and traceability for industrial-grade specifications.

AC DC Converters, Offline Switchers Selection Notes

Select this component when designing isolated power supplies requiring secondary-side feedback for optimal regulation. It must be used in conjunction with the LM3101 controller. Consider the requirement for a small pulse transformer with one or two turns on the primary and secondary windings to facilitate the necessary communication between the primary and secondary sides.

AC DC Converters, Offline Switchers Part Context

The LM3001M belongs to a regulator chip-set family developed for high-performance isolated power conversion. It complements the LM3101 secondary-side PWM controller to form a complete control solution. This pairing allows for voltage, current, or charge mode control while maintaining the fastest possible loop response for isolated switching regulators.
