LTM8029 36V , 600mA Step-Down IN Module Converter with 5A Quiescent Current FEATURES DESCRIPTION n Complete Switch Mode Power Supply The LTM 8029 is a 36V , 600mA step-down Module IN n Low Quiescent Current Burst Mode Operation converter with 5A quiescent current. It is an adjustable 5A I at 12V to 3.3V frequency buck switching regulator that consumes only Q IN OUT n 600mA Output Current 5A of quiescent current. The LTM8029 can accept an n Wide Input Voltage Range: 4.5V to 36V (40V ) input as high as 36V and operates at low input voltages MAX IN n Output Voltage: 1.2V to 18V due to its off-time skipping capability. Burst Mode opera- n Excellent Dropout Performance tion maintains high efficiency at low output currents while n Can Be Used as an Inverter keeping the output ripple low. The RUN pin features an n Adjustable Switching Frequency: 200kHz to 2.2MHz accurate threshold and the shutdown current is 0.9A. n Current Mode Control A power good flag signals when V reaches 90% of the OUT n SnPb or RoHS Compliant Finish programmed output voltage. n Tiny, Low Profile (11.25mm 6.25mm 3.42mm) The LTM8029 is packaged in a thermally enhanced, com- Surface Mount BGA Package pact (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 APPLICATIONS finish. n Automotive Battery Regulation All registered trademarks and trademarks are the property of their respective owners.
