Description

The LTM®8029 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 suitable for automated assembly by standard surface mount equipment. The LTM8029 is RoHS compliant.
