Features

? Dual output 3+1 or 2+2, or single output 4-phase

? 2.7V to 5.5V supply voltage

? 5A per phase output current capability

? Small solution size

? High efficiency (94 peak for 3.3V VIN, 1.8V VOUT,

L = 220nH)

? Low IQ in low power mode

? Proprietary control scheme reduces the output

capacitor and supports fast load transients (such as

50A/μs per phase)

? Voltage, current, and temperature telemetry through

integrated ADC plus auxiliary inputs

? ±0.7 system accuracy, remote voltage sensing

? I2C and SPI programmable output from 0.3V to 2.0V

? Independent Dynamic Voltage Scaling (DVS) for

each output

? Soft-start and fault detection (UV, OV, OC, OT),

short-circuit protection

? 4.7mmx 6.3mm 35 ball TFBGA with 0.8mm pin pitch
