High Efficiency Dual Cell Switched Capacitor Divider
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 overcurrent protection for increased system reliability without the need for external sensing components.
