• 1.6-V to 5.5-V input voltage range
– Device input voltage > 1.65 V for start-up
• 1.2-V to 5.3-V output voltage range (adjustable)
• High output current capability, 3-A peak switch
current
– 2-A output current for VIN ≥ 3 V, VOUT = 3.3 V
– 1.5-A output current for VIN ≥ 2.7 V, VOUT = 3.3
V
• High efficiency over the entire load range
– 8-μA typical quiescent current
– Power save mode
• 150-mV load-step response at a 1-A current step
• Peak current buck-boost mode architecture
– Seamless mode transition with < 20-mV output
ripple
– Forward and reverse current operation
– Start-up into pre-biased outputs
– Fixed-frequency operation with 2-MHz
switching
• Safety and robust operation features
– Overcurrent protection and short-circuit
protection
– Integrated soft start with active ramp adoption
– Overtemperature protection and overvoltage
protection
– True shutdown function with load disconnect
– Forward and backward current limit
• Small solution size
– Small 1-µH inductor
– Works with one 0805 output capacitor over the
full VOUT range
