Product Descriptions

IP5508 is a multi-functional power management SOC for total solution on Power Bank. It also integrates with boost converter, lithium battery charging management and battery level indicators.

IP5508 is highly integrated with abundant functions, which makes the total solution size minimized and BOM costed down.

IP5508 requires only one inductor to achieve buck and boost functions, DC-DC converter works at 500KHz and can support low-cost inductors and capacitors.

The synchronous boost system of IP5508 provides rated 2.4A output current with conversion efficiency up to 93 PERCENT. When there is no load, it will automatically enter the standby state, and the static current will drop to less than 100uA.

IP5508’s switch charging system supplies 2A charging current with charging efficiency up to 92 PERCENT. According to the IC temperature and input voltage, IP5508 can intelligently adjust charging current.

IP5508 contains 14bits ADC, which can accurately measure battery’s voltage and current. The built-in coulomb meter algorithm of IP5508 can accurately obtain the battery power information.

IP5508 can support digital tube display and illuminator function.

The package of IP5508 is QNF32.
