APPLICATIONS
1.GENERAL DESCRIPTION
There are 5 Switching Buck regulators 3 low power LDOs and 1 Power Switch that are all controlled and sequenced via the serial interface. The IC is equipped with all the standard protection features such as over current, over voltage and internal under voltage lock out protection. The serial interface is an I2C communication interface which allows supply sequencing as well as controlled supply ramp up and ramp down of all supplies except for the always on 1.5V LDO supplying to RTC load. The IC is offered in TQFN5x5-40 package. 2.APPLICATIONS
