Product Details

The LTM8029 is a 36VIN, 600mA step-down µModule® converter with 5µA quiescent current. It is an adjustable frequency buck switching regulator that consumes only 5μA of quiescent current. The LTM8029 can accept an input as high as 36VIN and operates at low input voltages due to its off-time skipping capability. Burst Mode operation maintains high efficiency at low output currents while keeping the output ripple low. The RUN pin features an accurate threshold and the shutdown current is 0.9μA. A power good flag signals when VOUT reaches 90% of the programmed output voltage.

The LTM8029 is packaged in a thermally enhanced, compact (11.25mm × 6.25mm) and low profile (3.42mm) overmolded ball grid array (BGA) package. The LTM8029 is available with SnPb (BGA) or RoHS compliant terminal finish.
