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)
(Switching frequency 2MHz(TYP))
All Buck Converters Support PFM/PWM Auto Mode.
12-Channel LDOs are Programmable to Voltage
Options by I2C.
LDOs and all Buck Converters Power ON/OFF
Control Enabled by I2C Interface or External pin.
2ch NMOS output LDOs (LDO11, 12) for Optimized
Efficiency.
Power ON/OFF Sequence.

(Note 1) The DVDD Voltage must be under the Battery voltage VBAT, PBAT anytimes.
(Note 2) Derate by 13.8mW/ when operation above Ta=25 (when mounted in ROHM’s standard board(54mm × 62mm)).
Caution: Operation the IC over the absolute maximum ratings may damage the IC. In addition, it is impossible to predict all destructive situations such as
short-circuit modes, open circuit modes, etc. Therefore, it is important to consider circuit protection measures, likes adding a fuse, in case the IC
is operated in a special mode exceeding the absolute maximum ratings.

(Note 3) Whenever the VBAT or PBAT or VIN1 or VIN2 voltage is under the LDO, SWREG output voltage,
or under certain levels, the LDO and SWREG output is not guaranteed to meet its published specifications.
It is necessary to supply the same voltage to PBAT and VBAT.
(Note 4) To achieve the best efficiency performance, SWREG5 output is recommended to be connected to VIN1 externally.
(Note 5) To achieve the best efficiency performance, SWREG4 output is recommended to be connected to VIN2 externally.
