Features, Applications

Complete Step-Down Switch Mode Power Supply nn Low Noise Silent Switcher® Architecture nn Wide Input Voltage Range: 40V nn Wide Output Voltage Range: nn 2.5A Continuous Output Current, 3.5A Peak nn Selectable Switching Frequency: 3MHz nn External Synchronization nn Programmable Soft-Start nn Tiny, Low Profile × 2.32mm RoHS Compliant BGA Package

DESCRIPTION

The 40VIN, 3.5A peak, 2.5A continuous step-down µModule® (power module) regulator. Included in the package are the switching controller, power switches, inductor and all support components. Operating over an input voltage range to 40V, the LTM8065 supports an output voltage range to 18V and a switching frequency range to 3MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the design. The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8065 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8065 is RoHS compliant.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Unless otherwise noted, the absolute minimum voltage is zero. Note 3: The LTM8065E is guaranteed to meet performance specifications from to 125°C internal. Specifications over the full to 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM8065I is guaranteed to meet specifications over the full 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 factors.

Note 4: The LTM8065 contains overtemperature protection that is intended to protect the device during momentary overload conditions. The internal temperature exceeds the maximum operating junction temperature when the overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 5: Below this specified voltage, internal circuitry will draw power from VIN. Note 6: PG transitions from low to high.
