DESCRIPTION
The
LTM
®
4661
is a synchronous step-up switching
mode µModule
®
(power module) regulator in a 6.25mm
× 6.25mm × 2.42mm BGA package. Included in the pack-
age are the switching controller, power FETs, inductor and
all support components. Operating over an input voltage
of 1.8V to 5.5V, down to 0.7V after start-up, the LTM4661
regulates an output voltage of 2.5V to 15V set by an exter-
nal resistor. It provides up to 4A switch current. Only bulk
input and output capacitors are needed.
The LTM4661 1MHz switching frequency and dual phase
single output architecture enable fast transient response
to line and load changes and a significant reduction of
output ripple voltage. It supports frequency synchroni-
zation, PolyPhase
®
operation and selectable Burst Mode
operation.
The LTM4661 features a true output disconnect during
shutdown and inrush current limit at start-up. It also has
short-circuit, overvoltage and overtemperature protection.
The LTM4661 is Pb-free and RoHS compliant.
