ADP5080:  Tiny 15V PMU with 6 CH DC/DCs and 2 LDOs for Multicell Lithium Ion Battery Applications

Product Details

Product Status:Recommended for New Designs

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.

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.

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.
