LTM4661 Description

The LTM4661 is a synchronous step-up switching mode μModule® (power module) regulator in a 6.25mm × 6.25mm × 2.42mm BGA package. Included in the package 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 external 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 synchronization, 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.
