E-L4960

Overview

The L4960 is a monolithic step-down switching regulator from STMicroelectronics, designed to deliver up to 2.5A output current with an adjustable voltage range of 5.1V to 40V. It operates within a minimum input voltage of 9V and supports switching frequencies up to 150kHz. The device features a precise on-chip reference with ±2% accuracy and includes integrated protection mechanisms such as thermal shutdown and internal current limiting. Packaged in the HEPTAWATT V through-hole format, it ensures high efficiency up to 90% while requiring minimal external components for implementation.

Feature Summary

Integrated soft start function for controlled power-up sequences
Built-in thermal shutdown and current limiting for enhanced reliability
Capable of 0 to 100% duty cycle operation for continuous mode performance

Applications

Industrial power supply systems
Battery-powered equipment charging circuits
General-purpose DC-DC conversion modules

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official STMicroelectronics documentation. Confirm package integrity and pin configuration match the HEPTAWATT V specification. Ensure that any ordering suffixes align with the required environmental or packaging variants. Check for end-of-life status or obsolescence notices prior to finalizing procurement decisions.

Selection Notes

Select this regulator when a robust, single-output buck converter is required for applications demanding up to 2.5A. Consider the 150kHz switching frequency for balancing component size and efficiency. Evaluate the thermal performance requirements given the through-hole package and ensure adequate heat dissipation is available in the target design environment.

Part Context

The L4960 belongs to the family of power switching regulators manufactured by STMicroelectronics. It serves as a solution for efficient voltage step-down applications, complementing other PMIC offerings. The device integrates control logic and power switches into a single monolithic structure, simplifying the design process compared to discrete solutions.
