1.2A High Efficiency Buck-Boost Regulators
ISL9110, ISL9112
The ISL9110 and ISL9112 are highly-integrated Buck-Boost
switching regulators that accept input voltages either above or
below the regulated output voltage. Unlike other Buck-Boost
regulators, these regulators automatically transition between
operating modes without significant output disturbance.
Both parts are capable of delivering up to 1.2A output current,
and provide excellent efficiency due to their 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 ISL9110 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 ISL9112 supports a broader set of programmable features
that may be accessed via an I
2
C bus interface. With a
programmable output voltage range of 1.9V to 5V, the ISL9112
is ideal for applications requiring dynamically changing supply
voltages. A programmable slew rate can be selected to provide
smooth transitions between output voltage settings.
The ISL9110 and ISL9112 require only a single inductor and very
few external components. Power supply solution size is
minimized by a tiny 3mmx3mm package and a 2.5MHz
switching frequency, which further reduces the size of external
components.

θ
JA
is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech

6. For
θ
JC
, the “case temp” location is the center of the exposed metal pad on the package underside.
7. LX1 and LX2 pins can withstand switching transients of -1.5V for 100ns, and 7V for 20ms.
