3 Introduction

IP5506 is an integrated boost converter and lithium battery charging tube

Multi-function power management SOC with management and battery power indication, for digital

Tube Display Power Bank provides a complete power solution.

The high integration and rich functions of IP5506 make it suitable for

Only a few peripheral components are required, and the size of the overall solution is effectively reduced.

Reduce BOM cost.

IP5506 only needs one inductor to realize the buck and boost functions.

The DC-DC converter operates at 500KHz and can support low-cost power

inductance and capacitance.

The IP5506's synchronous boost system provides a rated 2.4A output power

flow, and the conversion efficiency is as high as 93. When no load, automatically enters sleep state

state, the quiescent current drops to less than 100uA.

IP5506 adopts switching charging technology and provides rated 2A charging

current, the charging efficiency is as high as 92. Built-in IC temperature and input power

The voltage intelligently adjusts the charging current.

IP5506 has built-in 14bit ADC, which can accurately measure battery voltage.

and current. The IP5506’s built-in coulomb calculation provides accurate battery

Battery information.

IP5506 can support 5/4/3/2/1 LED power or digital tubes

Display and lighting flashlight functions.

IP5506 is available in ESOP16 package.
