APPLICATIONS DSLR cameras Non-reflex (mirrorless) cameras Portable instrumentation GENERAL DESCRIPTION
The ADP5080 is a fully integrated, high efficiency power All these features help to minimize the number of external solution for multicell lithium ion battery applications. The components and PCB space required, providing significant device can connect directly to the battery, which eliminates advantages for portable applications. The switching frequency the need for preregulators and, therefore, increases the battery is selectable on each channel from 750 kHz to 2 MHz. life of the system. Key functions for power applications, such as soft start, selectable The ADP5080 integrates two keep-alive LDO regulators, five preset output voltage, and flexible power-up and power-down synchronous buck regulators, a configurable four-switch buck sequences, are provided on chip and are programmable via the boost regulator, and a high voltage LDO regulator. The ADP5080 I2C interface with fused factory defaults. The ADP5080 is available is a highly integrated power solution that incorporates all power in a 72-ball WLCSP 0.5 mm pitch package. MOSFETs, feedback loop compensation, voltage setting resistor dividers, and discharge switches, as well as a charge pump to generate a global bootstrap voltage.
