1 LTM80631 Rev CFor more information FeedbackTYPICAL APPLICATIONFEATURESAPPLICATIONSDESCRIPTI ON40 VIN, 2A Silent Switcher Module RegulatorThe LT M 8063 is a 40 VIN, 2A continuous, peak, 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 LTM8063 supports an output voltage range of to 15V and a switching frequency range of 200kHz to , 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 LTM8063 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) pack-age suitable for automated assembly by standard surface mount equipment.

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 LTM8063E is guaranteed to meet performance specifications from 0 C to 125 C internal.

6 Specifications over the full 40 C to 125 C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM8063I is guaranteed to meet specifications over the full 40 C to 125 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 Input VoltageVIN DC VoltageRFB Open RFB = , VIN = 15V VPeak Output DC CurrentVOUT = , fSW = Current into VINRUN = 0V No Load, SYNC = 0V, Not Switching3 8 A ALine < VIN < 36V, IOUT = < IOUT < Voltage RippleIOUT = 2A15mVSwitching FrequencyRT = 232k.
