E-L6920D

Overview

The E-L6920D is a discontinued synchronous step-up converter manufactured by STMicroelectronics, housed in an 8-pin TSSOP package. It operates within an input voltage range of 0.6 V to 5.5 V and supports output voltages of 3.3 V, 5 V, or adjustable levels between 2 V and 5.2 V. The device features internal synchronous rectification with a 120 mΩ active switch and guarantees startup at 1 V. Designed for high efficiency, it utilizes variable frequency control and includes low battery detection and reverse battery protection capabilities.

Feature Summary

Internal synchronous rectifier implemented with a 120 mΩ P-channel MOSFET
Variable frequency control for improved efficiency
Low battery voltage detection functionality
Reverse battery protection

Applications

Battery-powered portable devices
Mobile phone power management
General DC-DC conversion from battery voltage

Procurement Notes

Verify component authenticity through authorized channels as the part is marked as obsolete. Confirm package integrity and moisture sensitivity handling requirements prior to installation. Cross-reference datasheet specifications against current design needs due to discontinuation status.

Selection Notes

Evaluate compatibility with existing boost converter topologies requiring low input voltage operation. Consider the fixed 120 mΩ internal switch characteristics when designing for specific load currents. Ensure external component selection aligns with the variable frequency control scheme for optimal performance.

Part Context

This component belongs to the L6920 series of high-efficiency step-up controllers. It shares functional similarities with variants like L6920DBTR but differs in packaging and specific electrical parameters. The series is designed for applications requiring minimal external components for battery-to-voltage conversion.
