The LTM®8063 is a 40VIN, 2A continuous, 2.5A peak, step- n
Wide Input Voltage Range: 3.2V to 40V
down µModule® (power module) regulator. Included in n
Wide Output Voltage Range: 0.8V to 15V
the package are the switching controller, power switches, n
2A Continuous Output Current at 12VIN, 5VOUT,
inductor, and all support components. Operating over an
TA = 85°C
input voltage range of 3.2V to 40V, the LTM8063 supports n
2.5A Peak Current
an output voltage range of 0.8V to 15V and a switching n Selectable Switching Frequency: 200kHz to 2.2MHz frequency range of 200kHz to 2.2MHz, each set by a single n External Synchronization resistor. Only the input and output filter capacitors are n Configurable as an Inverter needed to finish the design. n 6.25mm × 4mm × 2.22mm BGA Package The low profile package enables utilization of unused
