LTC3428 Datasheet (Linear Technology) - 2MHz Dual Phase Step-Up DC/DC Converter

LTC3428, 2MHz Dual Phase Step-Up DC/DC Converter

The LTC®3428 is a 2-phase, current mode boost converter, capable of supplying 2A at 5V from a 3.3V input.

Two 93mΩ, 2A N-channel MOSFET switches allow the LTC3428 to deliver high efﬁciency from input voltages as low as 1.6V.

External parts count and size are minimized by a 1MHz switching frequency a
