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 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.
Power Integrations has announced that PI Expert Suite — its flexible power supply unit (PSU) design tool — is now accessible as a cloud-based app.
Power Integrations has introduced the InnoSwitch series of integrated switcher ICs. The series combines primary, secondary and feedback circuits into a single, worldwide safety-rated, surface-mount package. The InnoSwitch series is suitable for smart mobile device chargers and adapters for a range of applications such as set-top boxes, networking equipment and computer peripherals.
Power Integrations has announced that its CAPZero range of two-terminal, automatic X-capacitor discharge ICs has been certified to meet IEC 62368, the new overarching safety standard covering televisions and IT equipment.
