钰泰 ETA1188 QFN-20 电池充电管理芯片

DESCRIPTION
EA1188is d high power, hig-ffciency, synchronous boost that can .
output up to 27W of power. With integrated high power MOSEFTs, it
comfotably 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 protetion and true shutoff functin. With its tiny package of 
QFN3x3- 20, it sports a small footprint which makes it an ideal al-in-one
solution for high power boost aplications.
The ETA1188 features a programmable output crrent 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 curent limit and output voltage
interall, making it suitable for Power Delivery or Quick Charge 
applications.
The ETA1188 is avilable in QFN33 20FC package.
