The LTC3428EDD#PBF is a 2-phase current-mode Boost Converter capable of supplying 2A at 5V from a 3.3V input. Two 93mR, 2A N-channel MOSFET switches allow the LTC3428 to deliver high efficiency from input voltage as low as 1.6V. External parts count and size are minimized by a 1MHz switching frequency and a 2-phase design. 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. Other features includes an active low shutdown pin reduces supply current to below 1µA, internal soft-start, anti-ringing control and thermal shutdown.
● 2-phase control reduces output voltage ripple
● Internal soft-start operation
● Uses small surface mount components
● Up to 92% high efficiency
