ETA1013
12W Output Power, Programmable Frequency up to 1MHz Step-Up Converter
DESCRIPTION
FEATURES
The ETA1013 is a high efficiency step-up converter that is capable
of delivering up to 12W of output power. Its switching frequency
can be externally programmed up to 1MHz. Current mode control
makes it suitable with low ESR small ceramic output capacitor
and provides small output current. Capable of delivering up to
2.1A of output current at 5V output from input down to 3V, it is an
ideal solution for applications with Li-Ion batteries, such as
portable power banks.
