Power Integrations (Nasdaq: POWI) 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” – Explains Peter Rogerson, senior director marcomms
At Power Integrations.
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.
“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 global safety and regulatory standards, including: UL1577 and TUV (EN60950), EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m).

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.
