Synchronous buck applications can take advantage of a pair of two-phase dc-dc power blocks that provide a choice of single or dual outputs. International Rectifier's iPowir iP2101 and iP2102 blocks come in a single BGA package that measures just 9.25 by 15.5 by 2.6 mm.

The iP2101 features an input of 3.14 to 5.5 V dc and an output of 0.8 to 2.5 V for a 3.3-V input, or 0.8 to 3.3 V for a 5-V input. The iP2102 has an input of 5.5 to 13.2 V and an output of 0.8 to 5 V for a 12-V input, or 0.8 to 3.3 V for a 6-V input. Both feature an interleaved input and can be operated in a single-ended mode (30-A output) or a dual mode (15-A output). They also operate from 200 to 400 kHz.

The iPowir devices provide overvoltage and overtemperature protection. Independent soft-start capability for each output enables various power-seeking and power-tracking options. In addition, a single control pin on each device enables an overcurrent hiccup or overcurrent latch function. The hiccup function is good for high-reliability systems that require immediate output-load voltage recovery once the short circuit is removed, maximizing system up-time and preventing overall system power from being recycled manually.

"Today's new generations of power-hungry ICs are forcing the use of more complex power-conversion devices than ever before. These products, the newest additions to the iPowir product family, offer the simplest path to the highest power density," says Gene Sheridan, International Rectifier's vice president for the Computing and Business Unit.

Available now, the iP1201 and iP1202 cost $10.05 each in 1000-unit lots.
