ETA1189
The ETA1189 is a high-efficiency, synchronous boost from a wide range input voltage to a wide range programmable output voltage. With integrated high power MOSFETs, it can deliver up to 9V/3.5A output. It also has the true-shutoff function and real short circuit protection. These features with its tiny package of QFN3x3-20 make it an ideal all-in-one solution for high power boost applications.
The ETA1189 features a programmable output current limit, set by a resistor connected from ISET pin to GND. The output voltage can be also programmed by a resistor divider from VOUT to FB pin to GND. Besides external configuration, the ETA1189 features I2C communication which can be used to configure the current limit and output voltage internally. These features make it suitable for power delivery or quick charge applications.
