Package Option

Fri, 09/28/2001 - 9:40am
Power Integrations announced the availability of a new surface mount package option for its TOPSwitch-GX product line, the industry's highest power monolithic switcher IC family. Eight new devices, ranging in power up to 82 watts, are now offered in the standard TO-263 surface mount package, also known as the D2PAK.

The new surface mount parts expand the recently announced TOPSwitch-GX family of switched mode power supply ICs that provide unparalleled design flexibility, high standby efficiency and lowest system cost. They are targeted for higher power applications where through-hole assembly is not an option due to height, layout, or manufacturing requirements. The TO-263 package also saves the cost of a heat sink by effectively delivering the heat directly to the printed circuit board. Typical applications include power adapters for laptops and LCD monitors, set-top boxes, and other low profile electronic equipment.

TOPSwitch-GX, introduced in late 2000, is a monolithic high-voltage IC family that cost effectively integrates a high voltage power MOSFET, PWM control, fault protection, and other control circuitry onto a single CMOS chip. Built-in features include soft-start for minimum overshoot and lower component stresses at start-up, frequency jittering for low EMI, under-voltage protection and overvoltage shutdown, current limit, and the company's energy saving EcoSmart technology. EcoSmart technology dramatically reduces energy consumption, especially in standby and "no load" conditions.
