High Efficiency 1.8A Boost Regulator With
Input-to-Output Bypass
ISL91132
The ISL91132 is an integrated boost switching regulator for
battery powered applications. The device provides a power
supply solution for products using a one cell Li-ion or Li-polymer
battery.
The device is capable of delivering up to 1.8A output current from
VIN = 2.5V and VOUT = 3.3V. The no-load quiescent current is only
108μA in Boost Mode and 45μA in Forced Bypass Mode, which
significantly reduces the standby consumption.
The ISL91132 offers a Bypass Mode operation where the output
is directly connected to the input through a 38mΩ MOSFET to
allow a significantly lower dropout voltage. The Bypass Mode can
be entered by an external command, or by auto bypass. The
Forced Bypass Mode allows the output voltage to operate close
to the input voltage and improves the efficiency under these
conditions.
The ISL91132 is designed to support 6 fixed output voltages
ranging from 3.15V to 5V. A voltage select pin is available for
each output variant to scale up the output voltage by a small
offset to compensate the load transient droop.
The ISL91132 requires only an inductor and a few external
components to operate. The 2.5MHz switching frequency further
reduces the size of external components.
The ISL91132 is available in a 16 bump, 0.4mm pitch,
1.78mmx1.78mm WLCSP.
Features
• Input voltage range: 2.35V to 5.4V
• Output current: up to 1.8A (VIN = 2.5V, VOUT = 3.3V)
• Burst current up to 2A (VIN = 2.5V, VOUT = 3.3V, tON < 600μs,
T = 4.6ms)
• High efficiency: up to 96%
• 108μA quiescent current minimizes standby consumption in
Boost Mode, 45μA in Forced Bypass Mode
• 2.5MHz switching frequency minimizes external component
size
• Forced Bypass or Auto Bypass Modes with a 38mΩ switch
• PFM mode at light-load currents
• Fully protected for overcurrent, over-temperature and
undervoltage
• Load disconnect when disabled
• Small 1.78mmx1.78mm WLCSP
Applications
• Smartphones and tablet PCs
• Wireless communication devices
