Ratings		 Description
HiperPLCTM PFC+LLC
Half-bridge		   HiperPLC™ is a combined PFC and LLC off-line controller with an integrated hi-side/lo-side high voltage half bridge driver. The PFC section of the HiperPLC supports a universal input, continuous-current mode (CCM) topology that does not require a sinusoidal input reference.
LinkSwitch®-II Flyback Up to 5.5 W Tight CV/CC, primary side control, capable of exceeding all energy efficiency specifications.
LinkSwitch®-TN Buck Up to 360 mA Energy-efficient capacitive drop replacement with minimal external component required
TinySwitch®-III Flyback Up to 28.5 W Improved design flexibility. Reduced input capacitance and transformer size due to on-time extension and I2f ratings.
TOPSwitch®-GX Flyback Up to 210 W Extended power range with UV detection, OV shutdown, externally programmable current limit and remote ON/OFF capability.
TOPSwitch®-HX Flyback Up to 254 W TOPSwitch-HX incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
