• Triple output 2+1+1 phases (ISL91301A) or quad
output single phase (ISL91301B)
• 4A per phase for the 2.8V to 5.5V supply voltage,
VIN_SEL = AVIN
• 3A per phase for the 2.5V to 5.5V supply voltage,
VIN_SEL = GND
• Small solution size
• High efficiency (93% for 3.8VIN/1.8VOUT)
• Low IQ in low power mode
• Proprietary control scheme reduces output capacitor and
supports fast load transient (such as 50A/μs per phase)
• ±0.7% system accuracy, remote voltage sensing
• Programmable PWM frequency from 2MHz to 6MHz
• I2C programmable output from 0.3V to 2V
• Independent Dynamic Voltage Scaling (DVS) for each output
• Soft-start and fault detection (UV, OV, OC, OT), short-circuit protection
• 2.570mmx2.919mm 42 ball WLCSP with 0.4mm pitch
