Acutechnology Patents Improved LDO Architecture

SAN JOSE, Calif., Jan. 24 -- Acutechnology Semiconductor Inc., innovators in power management, today announced the issue of the company's first patent, US6,989,659, "Low Dropout Voltage Regulator Using a Depletion Pass Transistor". The patented new technique allows the design of low dropout regulators with the performance of faster follower-based schemes, but without the need for extra bias supplies or charge pumps. This technology, dubbed QuikLDO&trade, is targeted at portable equipment where board space is at a premium and eliminating the output capacitor from an LDO gives a space advantage.

The patent, awarded to company founders Paolo Menegoli and Carl Sawtell, is the first of a series of patents being pursued by Acutechnology to protect its wide-ranging portfolio of power management techniques. Additional patent applications, including those for motor control and voltage reference circuits, are still being prosecuted with the US Patent and Trademark office.
