AN1201SM
Polarity inverting charge pump DC/DC converter IC
I Overview
AN1201SM is a negative voltage generation IC for
bias voltage of transmission power module of cellular
phones. This IC is a polarity inverting DC/DC converter
to change from positive voltage into negative voltage.
I Features
• High power conversion efficiency: 89% typ. (when output
current is 5 mA.)
• Low output resistance: 20 Ω typ.
• High voltage conversion efficiency: 99.9%
• Small (S-MINI) package
I Applications
• Cellular phones
