3 Introduction
IP6523S is a synchronous step-down
converter with built-in power MOSFETs. IP6523S
supports DCP protocols (BC1.2, Apple, Samsung),
providing total solution to car charger, fast charge
adapter and intelligent power hub applications.
IP6523S exhibits CV/CC characteristics. The
output in CV mode when the load current lower
than current limit, otherwise in CC mode, in which
the output voltage decreases as the load current
increases.
IP6523S supports output voltage
compensation due to the line loss. The output
voltage increases at 100mV@1A rate as the load
current increases.
IP6523S incorporates soft-start function to
prevent the inrush current during start-up.
IP6523S incorporates multiple safety
protections, such as input OV/UV, output
OV/UV/OC and SC protection.
The package of IP6523S is ESOP8.
