Switching ICs improve smart devices performance

This occurs while minimising overall thermal management and battery charging system cost.

The switching ICs are available in two models — the 15W-output INN2214K and 20W-output INN2215K — both of which incorporate a flyback controller, 650V MOSFET, secondary-side sensing, and synchronous rectification driver to provide extremely high efficiency across the full load range.

TheICs use Power Integrations’ 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 enables feedback information to be delivered across an isolation barrier without the use of magnetic materials, and delivers a very high communication bandwidth, which enables a much faster load-transient response.

Additionally, the minimal DC bias requirements of the integrated communication link, enable the system to achieve less than 10 mW (no-load).

The InnoSwitch-CP family of ICs dramatically simplify the development and manufacturing of low-voltage, high-current power supplies, particularly in compact enclosures or with high efficiency requirements.

The ICs incorporate a comprehensive suite of advanced protection features including overvoltage protection, output overcurrent protection with 3V auto restart, hysteretic thermal shutdown, and line input overvoltage protection with accurate brown-in/brown-out thresholds.
