High-voltage PWM buck converter sports small packaging

Westlake Village, Calif.—Diodes Inc.'s AP1580 300-KHz asynchronous PWM buck converter is housed in the company's latest packaging&#151 a thermally enhanced, SOP-8L that requires what the company says is five times less PCB area than the standard TO-220 or TO-263 packages typically used to support 3A drive currents.

The AP1580 with its wide input voltage range of 10V to 40V, and adjustable output voltage from 0.8V to 36V is well suited to support a variety of applications including LCD monitors and TVs, plasma display panels (PDP), power adaptors and battery chargers as well as high end networking and telecommunication equipment.

The AP1580 converter is fully integrated with an internal switch and is capable of delivering continuous output current up to 3A. Higher efficiency is obtained through the use of a low Rdson (80 milliOhms) NMOS power switch. The AP1580 converter has a 300-KHz fixed switching frequency, which allows the use of smaller external components.
