Three Step-Down DC/DC Converters
Four Low-Dropout Linear Regulators
I2CTM Serial Interface
This device features three step-down DC/DC
converters and four low-noise, low-dropout linear
regulators.
Advanced Enable/Disable Sequencing Controller
Minimal External Components
Tiny 5×5mm TQFN55-32 Package
− 0.75mm Package Height
− Pb-Free and RoHS Compliant
The three DC/DC converters utilize a highefficiency, fixed-frequency (2MHz), current-mode
PWM control architecture that requires a minimum
number of external components. Two DC/DCs are
capable of supplying up to 1100mA of output
current, while the third supports up to 1200mA. All
four low-dropout linear regulators are highperformance, low-noise, regulators that supply up to
150mA, 150mA, 250mA, and 250mA, respectively.
