 500mA Li-Ion Charger | | Beschreibung: | 500mA Li-Ion Charger with Integrated 600mA Synchronous Buck Converter
The EUP8080 is a complete constant-current/
constant-voltage linear battery charger for a single-cell
4.2V lithium-ion battery with an integrated 600mA
synchronous buck converter. It is specifically designed to
work within USB power specifications.
The battery charger offers an integrated pass device,
reverse blocking protection, high accuracy current and
voltage regulation, charge status, and charge termination.
The charging current is programmable via external resistor
from 15mA to 500mA. In addition to these standard
features, the device offers current limit, thermal protection,
and soft-start. The EUP8080 integrates a synchronous buck converter
that is powered from the BAT pin internally. It has an
adjustable output voltage and can deliver up to 600mA of
load current. The buck converter also features low-current
high-efficiency Power Save and low output ripple PWM
mode operation that can be selected by the MODE pin. | | | Dateigrösse: | 0 Bytes | | Hinzugefügt am: | 04-Mai-2009 | | Downloads: | 435 | | Kategorie: | Elektronik UpDownloads Datenblaetter | | Eintrag bewerten | Details |

| Op-Amp Circuit Collection | | Beschreibung: | All op-amps are differential input devices. Designers are accustomed to working with these inputs and connecting each to the proper potential. What happens when there are two outputs? How does a designer connect the second output? How are gain stages and filters developed? This application note will answer these questions and give a jumpstart to apprehensive designers. | | | Dateigrösse: | 0 Bytes | | Hinzugefügt am: | 06-Jun-2007 | | Downloads: | 204 | | Kategorie: | Elektronik UpDownloads Datenblaetter | | Homepage | Eintrag bewerten | Details |
