IP6536 is a synchronous step-down converter with built-in power MOSFETs. IP6536 supports DCP protocols (BC1.2, Apple and Samsung), providing total solution to car charger, charge adapter and intelligent power hub applications.
IP6536 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.
IP6536 supports output voltage compensation due to the line loss. The output voltage increases as the load current increases.
IP6536 incorporates soft-start function to prevent the inrush current during start-up.
IP6536 incorporates multiple safety protections, such as input OV/UV, output OV/UV/OC and SC protection.
The package of IP6536 is ESOP8.
