LTC3428EDD#PBF

LTC3428 is a 2-phase, current mode boost converter, capable of supplying 2A at 5V from a 3.3V input. Two phase operation significantly reduces peak inductor currents and capacitor ripple current, doubling the effective switching frequency and minimizing inductor and capacitor size. External compensation allows the feedback loop response to be optimized for a particular application. It is widely used in application such as networking equipment, handheld instruments, digital cameras, distributed power, local 3.3V to 5V conversion etc.

• High efficiency upto 92%
• 2-phase control reduces output voltage ripple
• 3.3V at 1.5A from 1.8V input
• 1.6V to 5.25V adjustable output voltage
• Input voltage range is 1.6V to 4.5V
• Internal soft-start operation
• Uses small surface mount components
• Shutdown current is 1μA maximum at (SHDN = 0V)
• Operating temperature is -40°C to 85°C
• Package style is 10-lead plastic DFN
