DESCRIPTION

· DA9313 is a high-voltage power converter with a maximum output current of 10 A, suitable for dual (2S) Li-ion or Li-polymer battery packs or input voltages between 5 V and 10.5 V.
· It operates with up to 98% efficiency and supports master/slave operation to double peak output current to 20 A.
· The device integrates pass devices, eliminating the need for external FETs, and features programmable soft start, over-temperature, and over-current protection.
· It offers configurable ports for enable, low power mode, and power good signals, supporting various power-up/down scenarios.

FEATURES

· 2S to 1S power voltage converter with 5 V to 10.5 V input voltage range.
· 10 A standalone output current, expandable to 20 A in master/slave configuration.
· Compact design with 1.0 mm max external component height and integrated power switches.
· I2C compatible interface and VOUT = ½ VIN.
· High efficiency up to 98%, with typical quiescent current of 55 μA (standalone) or 70 μA (master/slave).
· Package: 43 WL CSP (RouteEasy™, 0.65 mm pitch).

APPLICATIONS

· Ultrabooks™, Notebook computers, Chromebooks™, and Tablets.
· Smartphone direct charging and 2S battery applications.
· DSLR and mirrorless cameras, Camcorders, and Power banks.
