Developers of multi-cell, USB Type-C products that need higher current, dual input, and I²C support now have a flexible option with the MAX77756 24 V, 500 mA, low quiescent current buck converter from Maxim Integrated Products.
Products utilising the Power Delivery (PD) voltage range (5 V to 20 V) can generate an always-on (1,8 V/3,3 V/5,0 V) digital supply rail for the port controller. In addition, the device has a 20 μA quiescent current that extends battery life by reducing idle power consumption. To simplify the system design, the MAX77756 has a dual input ideal diode ORing circuit that allows the chip to power from the external USB source if the battery is empty.
