SAN JOSE, Calif., Aug. 9, 2017 /PRNewswire/ -- 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 24V, 500mA, low quiescent current (Iq) buck
converter from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

USB Type-C products must generate an always-on 3.3V rail to
detect USB insertions. Products utilizing the Power Delivery (PD)
voltage range (5V to 20V) can generate an always-on
(1.8V/3.3V/5.0V) digital supply rail for the port controller using
the MAX77756 step-down converter. In addition, the MAX77756 has a
20μA 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.
Multi-cell battery-operated devices—such as ultrabooks, laptops,
tablets, drones, and home automation appliances—can easily evolve
to Type-C with PD using the flexible MAX77756 power supply. The
MAX77756 has a unique combination of wide input voltage range, low
quiescent current, higher current load, dual input, and
I2C for flexibility and programmability. There is also a
default power mode if customers do not want to use the
I2C bus. The MAX77756 is a robust IC with short-circuit
and thermal protection, 8ms internal soft-start to minimize inrush
current, proven current-mode control architecture, and up to 26V
input voltage standoff.
Key Advantages
- Low quiescent current: 1.5μA Buck and 20μA MUX for
always-on operation
- High efficiency: Up to 92% with integrated power
MUX
- Small solution size: 2.33mm x 1.42mm 15-bump WLP; no
external Schottky array needed
- Wide input voltage: Operates on full VBUS range (5V-20V)
and VBATT (2S, 3S, 4S Li+)
Commentary
- "The MAX77756 saves board space and reduces series voltage drop
by integrating FETs, eliminating the need to use external Schottky
diodes," said Jia Hu, Executive
Business Manager, Mobile Power, Maxim Integrated. "The MAX77756
also helps engineers minimize power consumption and extend battery
life for the end application by offering highest efficiency and
lowest Iq compared to other products."
