Powering Minds of the Smart

10A Input, 9V/3A or 12V/2A Output BOOST Converter with True-Shutoff

DESCRIPTION

FEATURES

ETA1188 is a high power, high-efficiency, synchronous

boost that can output up to 27W of power. With

integrated high power MOSEFTs, it comfortably delivers

9V/3A output from a wide range of input voltage. It also

integrates an output short protection MOSEFT on chip to

provide over current protection and true-shutoff function.

With its tiny package of QFN3x3-20, it sports a small

footprint which makes it an ideal all-in-one solution for

high power boost applications.

The ETA1188 features a programmable output current

limit, configurable by a resistor connected from ISET pin

to GND. Output voltage can also be programmed by a

resistor divider from VOUT to FB to GND. Furthermore,

besides external configuration, ETA1188can also be

communicated through an I2C protocol to configure the

current limit and output voltage internally, making it

suitable for Power Delivery or Quick Charge applications.

The ETA1188 is available in QFN33-20FC package.
