ETA1189
ETA1189 is 9V/3.5A Output Synchronous Boost manufactured by ETA.
DESCRIPTION FEATURES 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 munication 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. The ETA1189 is available in a FCQFN3x3-20 package. - Wide Input Voltage Range, 3.1V to 9.5V - Wide Output Voltage Range, 3.6V to 12.6V - True Shutoff with 20mΩ n-Chanel Pass Device - Up to 95% High Efficiency - High Efficiency at Light Load - Programmable Current Limit, Output Voltage by External Resistor or Through I2C - Accurate Output Current with CC Loop Regulation - Up to 13A Cycle by Cycle Current Limit - Small Footprint: FCQFN3x3-20 package - Ro HS pliant APPLICATIONS - Quick Charge Mobile Power - Bluetooth Speaker Supply - Thunderbolt Interface - Electronic Cigarette TYPICAL APPLICATION 22u F VLDO SCL SDA 10n F 1u H 10K 10K 2 BOOT PMID 4 22u Fx2 5 SW PMID 12 7 SW VLDO 19 9 SW 11 SW 15 VIN ETA1189 VOUT 3 VOUT...
