IP5305 Description：
IP5305 is a multifunctional power management SOC that integrates a boost converter, lithium battery charging management, and battery level indication, providing a complete power solution for mobile power banks.
The high integration and rich functionality of IP5305 enable it to be applied with minimal peripheral components, effectively reducing the overall size of the solution and lowering BOM costs.
IP5305 only requires one inductor to achieve voltage reduction and boost functions. The DC-DC converter operates at 350KHz and can support low-cost inductors and capacitors.
The synchronous boost system of IP5305 provides a maximum output current of 1.0A and a conversion efficiency of up to 91%. When unloaded, it automatically enters sleep mode and the static current drops to 50uA.
IP5305 adopts switch charging technology, providing a maximum current of 1.2A and a charging efficiency of up to 93%. Built in IC temperature and input voltage intelligent adjustment of charging current.
IP5305 supports 1, 2, 3, and 4 LED power display.
IP5305 adopts eSOP8L packaging.
