LM2825 Datasheet Integrated Power Supply 1a DC-dc Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM2825 Integrated Power Supply 1A DC-DC Converter May 1997 LM2825 Integrated Power Supply 1A DC-DC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM2825 is a plete 1A DC-DC Buck converter packaged in a 24-lead molded Dual-In-Line integrated circuit package.

Contained within the package are all the active and passive ponents for a high efficiency step-down (buck) switching regulator.

Available in fixed output voltages of 3.3V, 5V and 12V, as well as two adjustable versions, these devices can provide up to 1A of load current with fully guaranteed electrical specifications.
