1 / 54 page  DA9313 High Efficiency Dual Cell Switched Capacitor Divider Datasheet Revision 3.0 07-Apr-2017 CFR0011-120-00 1 of 54 © 2017 Dialog Semiconductor General Description DA9313 is a high-voltage power converter with a maximum output current of 10 A, suitable for applications supplied from a dual (2S) Li-ion or Li-polymer stacked cell battery pack, or any input voltage between 5 V and 10.5 V. The converter operates with efficiency during conversion of up to 98 %. Master/slave operation is offered, where a pair of devices can combine to double the peak output current to 20 A. Low profile external components and a minimum PCB footprint allow small circuit implementation in compact applications. The pass devices are fully integrated therefore no external FETs are needed. DA9313 utilizes a programmable soft start to limit the inrush current from the input node and secure a slope controlled activation of the rails. It also implements integrated over-temperature and over- current protection for increased system reliability without the need for external sensing components. Enable, low power mode entry and exit, and power good signals are available at configurable ports flexibly supporting different applications and power-up or power-down scenarios.
