12W Output Power, Programmable Frequency up to 1MHz Step-Up Converter

DESCRIPTION

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.

ETA1013 is housed in an ESOP8 package.
