BD71801GWL
General Description
The BD71801GWL is an integrated Power Management
LSI available in a small 80-pins 0.4mm-pitch 3.8mm-by-
3.8mm Wafer-level CSP package, which is designed to
meet demands for space-constrained Smart phones.
The device provides 5-Buck Converters.
The device also includes 12 general-purpose LDOs
providing a wide range of voltage and current
capabilities.
All Buck Converters and LDOs are fully controllable by
the I2C interface. The BD71801GWL is very easy to use
in any mobile platforms.
Features
 5-Channel High Efficiency Step-down Converters.
(Adjustable Voltage Options by I2C)
