DESCRIPTION
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.
