The new LP8755 achieves a 70 mm2 total solution size, and supports up to 15 A from a 2.5-V to 5-V input with 90 percent efficiency.

The LP8755 converter with integrated FETs uses two I2C interfaces to manage dynamic voltage scaling, and features an automatic phase-adding and shedding technique to maintain the highest level of efficiency across a wide output current. During light load operation, the regulator enters a low-power mode as low as 10 uA (Iq) per converter core for maximum efficiency.
