The mobile equipment is evolving into smaller and more sophisticated equipment day by day.
This product has been developed as the multi-functional and small power management IC, in which the following functions are integrated into one chip: Power supply (Step-down DC/DC converter, 4-line LDO), Lithium-ion battery charge control, System reset, and Display white LED drive functions for the mobile equipment.
The type of package is QFN-32 whose size is 5mm by 5mm.

1.	Integrates into one chip the functions for the power supply system. Adopts small package (5mm square QFN-32) so that the packaging footprint of the set products can be reduced. (Reduces the packaging footprint by 33% from that of the power supply system that is composed of discrete ICs)
2.	Can cut cost by reducing the number of parts.
