GENERAL DESCRIPTION
The ADP5020 provides a highly integrated power solution that
includes all of the power circuits necessary for a digital imaging
module. It comprises two step-down dc-to-dc converters, one
LDO, and a power sequence controller. All dc-to-dc converters
integrate power pMOSFETs and nMOSFETs, making the system
simpler and more compact and reducing the cost. The ADP5020
has digitally programmed output voltages and buck converters
that can source up to 600 mA. A fixed frequency operation of
3 MHz enables the use of tiny inductors and capacitors. The buck
converters use a voltage mode, constant-frequency PWM control
scheme, and the synchronous rectification is implemented to
reduce the power loss. The Buck 1 regulator operates at up to
93% efficiency.

Information furnished by Analog Devices is believed to be accurate and reliable. However, no

The ADP5020 provides high performance, reduces component
count and size, and is lower in cost when compared to conven-
tional designs.
The ADP5020 runs on input voltage from 2.4 V to 5.5 V and
supports one-cell lithium-ion (Li+) batteries. The high perfor-
mance LDO maximizes noise suppression. The ADP5020 can be
activated via an I 2 C? interface or through a dedicated enable input.
During logic-controlled shutdown, the input is disconnected
from the output source, and the part draws 1 μA typical from
the input source. Other key features include undervoltage lockout
to prevent deep-battery discharge and soft start to prevent input
current overshoot at startup. The ADP5020 is available in a
20-lead LFCSP.
