PI new LinkSwitch-HP IC can provide the primary power supply for the 90 W power supply to the primary side voltage regulator (PSR)

Pioneering primary side voltage regulator technology can be omitted in high power applications optocoupler feedback circuit to achieve 30 mW no-load power consumption and efficient standby

For high voltage integrated circuit industry high efficient power conversion of the leader of the Power Integrations company (NASDAQ: POWI) today announced the launch of the new high efficiency, off-line switching IC products - LinkSwitch -HP, the highest output power series devices up to 90 W and can realize the primary side regulated precision (PSR).

LinkSwitch-HP IC uses an innovative control algorithm and use characteristics of main power transformer and the output diode (instead of optocoupler and feedback circuit), to determine the amount of power transmitted from the primary side to the secondary side of the isolation. This method can greatly reduce the number of components, not only save space and cost, but also enhance the reliability. More than and 10 years ago, with the launch of Power Integrations LinkSwitch series of products, PSR began to spread, is now the standard mobile phone charger and many low power applications, but until now, it is still lack of high precision constant pressure power products required. The LinkSwitch-HP device uses a unique multi-mode control architecture that substantially improves the technical level of the PSR, making it a viable method for power applications ranging from 9 W to 90 W.

Power Integrations vice president of marketing Doug Bailey said: Power Integrations is the first launch of integrated primary side off line switching device company. From the mobile device charger to LED lighting, to the electrical bias power supply, and even smart meter extremely low power is widely used in LinkSwitch products are currently using PSR technology than any similar products are more hot. The LinkSwitch-HP device will power range of PSR was extended to 90 W, the designer could apply the advantages of the PSR tablet computer, super charger adapter, LCD monitors and televisions, set-top boxes, home appliances and embedded power applications. The power and performance provided by LinkSwitch-HP IC is unmatched by any other PSR solution. "

The LinkSwitch-HP device can automatically according to the control mode of the dominant line voltage and load conditions, so as to optimize the conversion efficiency and fast transient response to load requirements, at the same time can reduce the output ripple and audio noise. Continuous conduction mode (CCM) operation can reduce the RMS current, and thus improve efficiency and reduce heat dissipation, while the 132 kHz full load frequency also allows the use of smaller cores and LC post filter components. LinkSwitch-HP IC can load power consumption under 230 VAC to achieve less than 30 mW, and the efficiency in the input power level of 0.1 W reached more than 50%, and easily meet all global energy efficiency regulations, such as ErP (EuP), Tier ENERGY STAR EPS external power supply V2.0 and EC eco design directive 2 requirements.

The LinkSwitch-HP device can also meet the safety standards of GB 4943.1-2011 in China to reduce cost and complexity, the standards must not meet the stringent requirements of creepage distance and clearance power add warning labels. The new law is similar to the UL 60950-2007, will be enforced in December 1, 2012, which requires for at an altitude of 2000 meters above the use of equipment to improve the primary side of the power - secondary side clearance (multiplied by the multiplier of 1.48), you must add a warning label on the product.

The LinkSwitch-HP IC has a wide range of protection features, including optional current limiting points, programmable turn off delay time extension, and voltage sag, voltage sag, overvoltage, overcurrent and over temperature protection. Now the existing engineering samples, production is expected by the end of August 2012 start. LinkSwitch-HP devices offer two different packaging options: eSIP-7C and eDIP-12B, based on the order of $10000 per unit price of $0.42 per piece (LNK6763V). Now we can also support two kinds of assessment demonstration board provides according to the customer's requirements: RDK-321 (for LCD display 17 W dual output flyback converter) and RDK-313 (30 W, 12 V single output adapter).
