Constant power profile pairs with Qualcomm Quick Charge, USB-PD and
other adaptive-voltage protocols
Power Integrations (Nasdaq:POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced its InnoSwitch™-CP
family of off-line CV/CC flyback switching ICs. The new devices
incorporate a constant power output profile which, when paired with an
adaptive-voltage protocol such as Qualcomm® Quick Charge™ 3.0 or USB-PD,
permits smart mobile device makers to optimize charging time across a
range of products. Developers employing adaptive charging technology
achieve dramatically faster charge times, improved charging efficiency
and backward compatibility with the popular 5 V USB BC 1.2
specification, all while minimizing overall thermal management and
battery charging system cost.

InnoSwitch-CP ICs use Power Integrations’ innovative FluxLink™
technology which enables high-performance secondary-side control to be
implemented with the simplicity and low component count usually
associated with primary-side regulation. FluxLink technology also
optimizes the effectiveness of output synchronous rectification,
resulting in extremely high efficiency across the full load range. For
example, no-load consumption at 230 VAC is less than 10 mW, while
full-load efficiency exceeds 90%. InnoSwitch-CP devices easily meet all
global energy efficiency regulations.
Explains Shyam Dujari, director of product marketing at Power
Integrations: “The cost of a charger is proportional to its power
rating, but the voltage and current required for optimal fast charging
of the battery is dependent on factors such as battery size, chemistry
charge level and the thermal environment. By providing a constant power
output, InnoSwitch-CP allows battery-operated devices to draw up to the
maximum power of the charger at any selected output voltage, optimizing
charge time and cost. This allows OEMs to offer consumers shorter charge
times and increased device availability, while simplifying the accessory
supply chain.”
InnoSwitch-CP
ICs incorporate a comprehensive suite of advanced protection features
including: OVP; output OCP with 3 V auto restart; hysteretic thermal
shutdown and line input overvoltage protection with accurate
brown-in/brown-out thresholds. Devices are fully compliant with safety
and regulatory standards, including: 100% production HIPOT compliance
testing equivalent to 6 kV DC/1 sec; reinforced insulation; and
isolation voltage testing to above 3,500 VAC. They are UL1577 and TUV
(EN60950) safety approved and EN61000-4-8 (100 A/m) and EN61000-4-9
(1000 A/m) compliant.
Two devices are available. The INN2214K IC delivers 15 W output power
for universal voltage chargers and adapters, while the larger INN2215K
part delivers up to 22 W for similar applications. InnoSwitch-CP
samples are available now. Devices are priced at $0.90 in 10,000-piece
quantities. For more information please visit www.power.com/innoswitch-cp/.
