1.2A High Efficiency Buck-Boost Regulator
ISL9110A
The ISL9110A is a highly-integrated Buck-Boost switching
regulator that accepts input voltages either above or below the
regulated output voltage. Unlike other Buck-Boost regulators, this
regulator automatically transitions between operating modes
without significant output disturbance.
This part is capable of delivering up to 1.2A output current, and
provides excellent efficiency due to its fully synchronous 4-switch
architecture. No-load quiescent current of only 35μA also
optimizes efficiency under light-load conditions. Forced PWM
and/or synchronization to an external clock may also be selected
for noise sensitive applications.
The ISL9110A is designed for standalone applications and
supports 3.3V and 5V fixed output voltages or variable output
voltages with an external resistor divider. Output voltages as low
as 1V, or as high as 5.2V are supported using an external resistor
divider.
The ISL9110A requires only a single inductor and very few
external components. Power supply solution size is minimized by
a 2.4mm x 1.6mm WLCSP package and a 2.5MHz switching
frequency, which further reduces the size of external
components.
