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 introduced the HiperPFS-3 series of power-factor-correction ICs. The ICs are designed to offer high power factor and high efficiency across the entire load range. Suitable for applications with continuous power demands up to 405W for universal input and 900W for high line, the ICs feature efficiency levels of better than 95 per cent from 10 per cent load to full load and consume less than 60mW under no-load conditions. A power factor of above 0.92 is easily achievable ...
Power Integrations has launched the CAPZero-2 ICs, the next generation of its CAPZero line of two-terminal, X capacitor discharge ICs. CAPZero-2 ICs increase design flexibility by covering a wide range of applications and output power.
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.
