GENERAL DESCRIPTION

The ADP5080 is a fully integrated, high efficiency power

solution for multicell lithium ion battery applications. The

device can connect directly to the battery, which eliminates

the need for preregulators and, therefore, increases the battery

life of the system.

All these features help to minimize the number of external

components and PCB space required, providing significant

advantages for portable applications. The switching frequency

is selectable on each channel from 750 kHz to 2 MHz.

Key functions for power applications, such as soft start, selectable

preset output voltage, and flexible power-up and power-down

sequences, are provided on chip and are programmable via the

I²C interface with fused factory defaults. The ADP5080 is available

in a 72-ball WLCSP 0.5 mm pitch package.

The ADP5080 integrates two keep-alive LDO regulators, five

synchronous buck regulators, a configurable four-switch buck

boost regulator, and a high voltage LDO regulator. The ADP5080

is a highly integrated power solution that incorporates all power

MOSFETs, feedback loop compensation, voltage setting resistor

dividers, and discharge switches, as well as a charge pump to

generate a global bootstrap voltage.
