Intersil Launches Advanced PWM + Linear Combo Power Controller
-- New Endura controller provides high performance, space savings and low BOM~-- Power controller offers high efficiency from 5- to 24-V supplies for wide range of applications
IRVINE, CA, September 10, 2002 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today announced the new Endura ISL6226 synchronous buck PWM plus linear low-dropout (LDO) combo controller. The ISL6226 controller reduces parts count and saves board space while offering the industrys lowest bill of materials.
The wide operating voltage range of 5- to 24-V makes this advanced dual controller an ideal choice to power chip sets, memory, audio and graphics in a wide range of portable and fixed information appliances. Target applications include notebook PCs, web tablets, portable data terminals, point-of-sale terminals, portable instruments, LCD-PCs and blade servers.
The ISL6226 provides a low-cost and flexible power solution with both an advanced PWM controller and a linear LDO regulator in a single 24-lead SSOP package. Component count and costs of the solution design are reduced because no current sense resistor is needed, no discrete Schottky diode is needed parallel to the lower MOSFET and there is only one 5-V power pin, which eliminates one bypass capacitor and a resistor. In addition, only a single resistor is needed for current-limit protection. The ISL6226 delivers excellent dynamic response, thermal shutdown protection, and high efficiency during light load operation.
