High-current regulator reduces PCB size 70%

The IR3847 high-current PoL integrated voltage regulator is a third-generation design that extends the current rating to 25 A in a 5 x 6-mm package. A thermally enhanced package uses a copper clip and several proprietary innovations that enable the device to operate at 25 A without a heatsink, and reduces PCB size by 20% compared to alternative integrated solutions and 70% compared to discrete solutions. A complete 25-A power supply solution can be implemented in 168 mm2

The PoL regulator integrates power MOSFETs with a controller (starting at $2.23 ea/100,000) that includes post-package precision dead-time trimming, and an internal LDO to optimize efficiency across the entire load range. 0.5% reference voltage accuracy from 25° to 105°C, and output voltage accuracy
