DC/DC Controller Supports High-Current Devices
Linear Technology Corp.

The LTC3877 dual output multiphase synchronous step-down dc/dc controller with 6-bit voltage identification (VID) control delivers a 10-mV output voltage step resolution, a necessary feature when powering high-current FPGAs and ASICs with tight input voltage requirements. It operates over an input voltage range of 4.5V to 38V and produces a fixed output voltage from 0.6V to 1.23V when using VID and up to 5V without VID. Up to 12 phases can be paralleled and clocked out-of-phase. When outputs are paralleled, the LTC3877 maintains better than ±2.5% current mismatch between phases, making it viable for current requirements up to 300A. Available in a 44-lead, 7 mm x 7 mm QFN package, price starts at $3.94 each/1,000. For more info, visit http://www.linear.com/product/LTC3877
