ISL91110IINZ-T

开关稳压器 Buck-Boost Reg with 4A Switches, 3.3V

High Efficiency Buck-Boost Regulator with 5.4A Switches

The ISL91110IINZ-T ISL91110IR is a high-current buck-boost switching regulator  for systems using new battery chemistries. It uses Intersil’s  proprietary buck-boost algorithm to maintain voltage regulation  while providing excellent efficiency and very low output voltage  ripple when the input voltage is close to the output voltage.

Features ISL91110IINZ-T

• Accepts input voltages above or below regulated output

voltage

• Automatic and seamless transitions between buck and

boost modes

• Input voltage range: 1.8V to 5.5V

• Output current: up to 2A (PVIN = 3.4V, VOUT = 5V)

• Output current: up to 2A (PVIN = 2.5V, VOUT = 3.3V)

• Burst current: up to 3A (PVIN = 2.9V, VOUT = 3.3V, tON <

600μs, t = 4.6ms)

• High efficiency: up to 95%

• 35μA quiescent current maximizes light load efficiency

• 2.5MHz switching frequency minimizes external component

size

• Fully protected for short-circuit, over-temperature and

undervoltage

• Small 4mmx4mm 20 Ld TQFN package

Applications ISL91110IINZ-T

• Smartphones and tablet PCs

• Wireless communication devices

• Optical modules networking equipment
