LTC3869 Datasheet (Linear Technology) - 2-Phase Synchronous Step-Down DC/DC Controllers

LTC3869, 2-Phase Synchronous Step-Down DC/DC Controllers

The LTC®3869 is a high performance dual synchronous step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages.

A constant frequency current mode architecture allows a phaselockable frequency of up to 780kHz.

Power loss and noise due to the ESR of the input ca
