40VIN, 2.5A Silent Switcher µModule Regulator - …

1 LTM80021 Rev 0 For more information APPLICATION FEATURESDESCRIPTION40 VIN, Silent Switcher Module Regulator The LT M 8002 is a 40 VIN, step-down Module (power module) Regulator . Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of to 40V, the LTM8002 supports an output voltage range of to 18V and a switching frequency range of 200kHz to 3 MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.

2 The LTM8002 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8002 is available with SnPb or RoHS compliant terminal finish.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and 2: Unless otherwise noted, the absolute minimum voltage is 3: The LTM8002I is guaranteed to meet specifications over the full 40 C to 125 C internal operating temperature range.

6 The LTM8002H is guaranteed to meet specifications over the full 40 C to 150 C internal operating temperature range. Note that the maximum internal temperature is determined by specific operating conditions in conjunction with board layout, the rated package thermal resistance and other environmental factors. High junction temperatures degrade operating lifetimes.
