Power Integrations announced the availability of its TOPSwitch-HX series of AC/DC power conversion ICs in the new eSIP-7C Eco-Single-Inline-package (eSIP).

This package exhibits the same low thermal impedance as the traditional TO-220, yet stands less than 10mm above the PCBhalf the height of the 45-year old package. eSIP-based designs reduce the overall height of the power supply in support of increasing market demand for slimmer electronic products such as LCD monitors, flat screen TVs and STBs.

As with all Power Integrations products, the heatsink attached to the eSIP package is at Source potential and therefore electrically quiet without the use of an insulating pad, reducing system EMI and assembly cost. In addition to thermal and physical size benefits, the eSIP package also reduces power supply manufacturing costs, the company said.

An easy-to-use, low-cost clip reduces heatsink assembly time and improves package to heatsink contact repeatability.

The clip-mounted eSIP passes shock and vibration tests to IEC 60068.
