Battery Chargers datasheet and documents for LM3622AM-8.2/NOPB

LM3622AM-8.2/NOPB

Battery Chargers Overview

The LM3622AM-8.2/NOPB is a high-efficiency synchronous step-down DC/DC converter manufactured by Texas Instruments. It integrates two N-channel power switches and operates with an input voltage range of 2.7V to 5.5V. The device delivers a fixed output voltage of 8.2V, supporting up to 1A of continuous load current. Key electrical specifications include a switching frequency of 1.5MHz, typical efficiency exceeding 90%, and a quiescent current of 140µA. It features adjustable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection within a compact 10-pin WQFN package.

Battery Chargers Feature Summary

Integrates dual N-channel power switches for high-efficiency synchronous rectification
Provides fixed 8.2V output with integrated feedback network
Includes programmable soft-start to limit inrush current during startup

Battery Chargers Applications

Portable electronic devices requiring stable 8.2V rails
Battery-powered systems with single-cell lithium-ion inputs
Embedded industrial control modules

Battery Chargers Procurement Notes

Verify the specific suffix 'AM' against the official datasheet to confirm pinout and functional compatibility. Ensure the 'NOPB' designation matches RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's latest product change notification to validate component availability and lifecycle status before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a fixed 8.2V output is required from a low-voltage source without external feedback resistors. Consider the 1.5MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate the 1A current capability against peak load demands to ensure adequate thermal performance within the specified operating temperature range.

Battery Chargers Part Context

This part belongs to the LM3622 family of synchronous buck converters designed for space-constrained applications. It complements other variants in the series that offer different fixed output voltages or adjustable regulation options. The device utilizes Texas Instruments' proprietary high-speed gate drive technology to optimize conversion efficiency across varying load conditions.

Battery Chargers Replacement Considerations

Direct substitutes may include other LM3622 variants with compatible output voltages or packages. Verify pin-to-pin compatibility and electrical parameters such as switching frequency and current limits before substitution.
