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.

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 I²C® 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.
