Reference design enables highest efficiency
solution in chargers for smartphones and tablets
ON Semiconductor (Nasdaq: ON), driving energy efficiency
innovations, has introduced a reference design implementing the new
Qualcomm® Quick Charge™ 3.0 protocol. The new protocol provides
significant efficiency improvements over the existing Quick Charge
2.0 solution. The high efficiency, small form factor reference
design supports the Quick Charge 3.0 High Voltage Dedicated
Charging Port (HVDCP) Class A and Class B specifications,
Qualcomm’s next generation of fast charging technology for
smartphones and tablets, as well as offering backward compatibility
to the older Quick Charge 2.0 protocol. Qualcomm Quick Charge 3.0
technology is a product of Qualcomm Technologies, Inc., a
subsidiary of Qualcomm Incorporated. The availability of a complete
reference design from ON Semiconductor as well as certified
conformance from UL aids the rapid development of small form factor
chargers for portable applications with industry leading
efficiency.
The reference design highlights the new NCP4371 secondary side
charge controller, which allows the charger USB-bus voltage to be
changed based on requests from the phone or portable device. To
optimize the battery charging time, the USB-bus voltage can be
controlled in discrete steps from 3.6V up to 20V. The new charge
controller is also suited for use in A4WP wireless charging
applications where the voltage can be optimized based on the
transmit (TX) portion of the reference design.
The NCP4371 also removes the need for a secondary shunt
regulator, saving cost and the space required to implement a
charger design. The primary side controller is the NCP1361 PSR
quasi-resonant PWM controller and the synchronous rectification
controller is the NCP4305. The combination of these two controllers
enables a high efficiency design meeting CoC Tier-2 requirements
for chargers.
“Fast charging capability is quickly gaining acceptance at all
portable device manufacturers,” said Shane Chilton, director of the
AC-DC business unit at ON Semiconductor. “We are excited to be
working with Qualcomm on this next generation power solution which
ties in with our strategy of delivering innovative high efficiency
solutions to our customers.”
Packaging and Pricing
The NCP4371 is offered in a SOIC-8 package and priced at $0.18
USD per unit in 10,000 unit quantities.
