E-L6926

Overview

The E-L6926 is a monolithic DC-DC synchronous step-down switching voltage regulator manufactured by STMicroelectronics. It operates with an input voltage range of 2 V to 5.5 V, making it suitable for single Li-Ion cell applications. The device delivers a maximum output current of 800 mA and features an adjustable output voltage starting from 0.6 V. It utilizes a fixed 600 kHz current-mode architecture with pulse width modulation. Key electrical parameters include a maximum shutdown supply current of 1 µA, ±1% output voltage accuracy, and thermal shutdown protection at 150 °C. The component is available in an 8-pin MSOP or TSSOP package.

Feature Summary

Internal synchronous switch eliminates the need for external Schottky diodes
Low-dropout operation enabled by duty cycle saturation up to 100%
Externally clock-synchronized capability for noise-sensitive environments
Integrated Power Good signal and overvoltage protection

Applications

Single Li-Ion cell supplied portable electronics
Battery-powered consumer devices requiring high efficiency
Noise-sensitive systems utilizing external synchronization

Procurement Notes

Verify the specific suffix (e.g., Q1TR, D1013TR) against the required package type and automotive qualification status. Confirm RoHS compliance and lead times with authorized distributors. Ensure the selected variant matches the intended operating temperature range and pin configuration for PCB layout compatibility.

Selection Notes

Select this regulator for designs requiring high efficiency and low quiescent current in space-constrained applications. Consider the 600 kHz switching frequency for passive component size optimization. Evaluate the external synchronization feature if system-wide noise management is critical. Verify that the 800 mA output current meets the load requirements under all operating conditions.

Part Context

The L6926 series comprises high-efficiency monolithic synchronous buck converters designed for battery-operated equipment. The family includes variants with different packaging options such as VFQFPN and VFSON, catering to diverse board space constraints. These regulators are characterized by their ability to operate efficiently across a wide input voltage range while maintaining precise output regulation.
