Features
• Dual output 3+1 or 2+2, or single output 4-phase
• 2.5V to 5.5V supply voltage
• 5A per phase output current capability
• Small solution size
• High efficiency (94.7% peak for 3.8V VIN, 1.8V
VOUT, L = 470nH)
• 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 with remote voltage sensing
• OTP programmable PWM frequency from 2MHz to
6MHz
• 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
• 2.551mmx 3.670mm 54 ball WLCSP with 0.4mm pin
pitch
