Power-supply ICs designed for slim LED-backlit TVs and PC main power systems
Power Integrationscontact supplier
Power Integrations has introduced HiperLCS, a range of high-voltage LLC power-supply ICs that incorporate the controller, high- and low-side drivers and both MOSFETs into a single package, making them suitable for applications such as slim LED-backlit TVs, PC main power, servers, telecoms and networking equipment, LED streetlights and laser printers.
HiperLCS devices provide all the required functions in a single IC, thereby streamlining the design cycle, saving board space, reducing assembly costs and increasing reliability.
The high switching frequency of HiperLCS devices allows designers to use low-cost SMD ceramic capacitors in the output loop instead of bulky, unreliable electrolytic capacitors, and reduces the size of the magnetics required.
- Maximum efficiency of better than 97 per cent
- Operation up to 750kHz
- New thermally efficient, low-profile eSIPe-16C package further contributes to space savings and reduces heat sink size
- Resonant control circuitry provides very low power loss
- Designs exceed benchmarks set by Energy Star N 4.0 and 5.0, and the 80 PLUSP Gold and Platinum PC efficiency standards
- HiperLCS devices allow users to set circuit parameters such as dead time and soft start
- Design process is assisted by PI XLSL, a real-time design and modelling tool
Power Integrations has launched the 2SC0115T2A0-12 dual-channel gate-driver core for 90kW to 500kW inverters and converters. Leveraging SCALE-2 integrated circuit and isolated transformer technology for DC/DC power and switching signal transmission, the new driver core improves system reliability and performance by eliminating the need for an optocoupler.
DER-479 demonstrates an industrial power supply using the LinkSwitch-4 series of CV/CC primary-side regulated switcher ICs with a 1,200V bipolar junction transistor.
Power Integrations has announced the arrival of the RDK-420, a reference design kit for a 10W CV/CC USB charger based on the company’s InnoSwitch-CH family of highly integrated switcher ICs. InnoSwitch ICs combine the primary-side switch together with primary and secondary controllers and feedback circuits into a single, worldwide safety-rated, surface-mount package.
Power Integrations has launched its latest SCALE-2+ dual-IGBT driver core, the 2SC0435T2G1-17, which is described as the most compact product in its power range with a footprint of only 57.2 x 51.6mm and a height of just 20mm.
Power Integrations has released a new series of Qspeed 150V diodes. Qspeed LQA150 series silicon diodes are claimed to be very fast and feature excellent softness for low EMI.
