Constantpower profile pairs with Qualcomm Quick Charge, USB-PD and other adaptive-voltage protocols
Shenzhen, China – January14, 2016– 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 constantpower 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 5V USB BC 1.2 specification,allwhile 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 implementedwith the simplicity and low componentcount usually associated with primary-side regulation. FluxLink technology alsooptimizes 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 dependenton 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 ICsincorporate a comprehensive suite of advanced protection features including: OVP; output OCP with 3V auto restart; hysteretic thermal shutdown and line input overvoltage protectionwith 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 15W 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. Devicesare priced at $0.90in 10,000-piece quantities. For more information please visit www.power.com/innoswitch-cp/.
