​3 Introduction

IP6537U is a synchronized switch buck regulator which supports multiple fast charge output protocols,providing solutions for car charger and charge adaptor.
IP6537U has built-in power MOSFET, input voltage range is 7.2V to 32V, output voltage ranges from 3V to 21V, and supply up to 45W output power, can
automatically adjust the output voltage and current according to the identified fast charging protocol. IP6537U output power has CV/CC characteristic.
when the output current islower than the preset value, it is in CV mode with a constant output voltage; when the output current is higher than the preset value, it
enters CC mode and the output voltage decreases as the output current increases. The PIN15 and PIN16 of IP6537U can be used as intelligent power reduction control function,
connecting two external resistances can simply use two IP6537U to realize dual-port intelligent power reduced function. IP6537U supports soft start, providing resistibility
on the large inrush current during circuit start up. IP6537U supports multiple protection on input overvoltage and under voltage, output overcurrent, overvoltage, under voltage and short circuit.
