Power regulators for DDR applications

22 August 2007 Power Electronics / Power Management

Freescale has introduced a series of single- and dual-power regulator ICs that provide efficient power management for double-data-rate (DDR) applications. The MC34712/3/6/7 regulators efficiently power data-dense DDR1/2/3 memory systems and handle DC/DC conversion in a wide range of power conversion applications.

Operating as synchronous buck switching converters, these regulators are designed to increase power management efficiency by up to 93% in most DDR applications, and with less power dissipation for DC/DC conversion. They provide programmable high-current switching frequency of up to 1 MHz for smaller inductors and capacitors.

Manufactured with Freescale's SMARTMOS technology, the MC34712/3/6/7 series features an integrated controller and MOSFETs. This high level of integration minimises the need for external components and helps reduce the total component count for space-constrained applications.

The devices accept input voltages between 3,0 and 6,0 V, offer a programmable switching frequency from 200 kHz to 1 MHz and provide output voltage accuracy of ±2%.
