Intersil Announces ISL6534 Three-in-One Controller
Intersil Corp. (Milpitas, CA) announced its new ISL6534, a high-efficiency, cost-competitive, three-in-one PWM solution for providing two synchronous buck voltage outputs and a linear controller output. The device powers next-generation double data rate (DDR) memory supplies for servers, motherboards, I/Os, FPGAs and embedded processors, as well as, graphic cards and other system electronics.
The new triple regulator has two independent synchronous-rectified buck controllers with integrated 12 V gate drivers and a linear controller, which provides precision regulation of up to three voltage rails. Each output has an internal 0.8% accurate reference for regulating any voltage down to as low as 0.6 V. An optional shunt regulator allows 12 V-only operation, when a 5 V supply is not available. When configured in DDR mode, the ISL6534 offers a low-cost bill-of-materials solution for powering DDR memory by including Vddq to Vtt tracking, and a VREF-buffered output, as well as an additional linear output.
The ISL6534 is available now in a standard lead finish and a lead-free finish, and either a 32-lead, thermally enhanced, 5 mm x 5 mm QFN package or a 24-lead, exposed pad TSSOP package. Pricing in 10,000-unit quantities is $1.50 for each IC.
