LTC3890 - 2-Phase Synchronous Step-Down DC/DC Controller

The LTC®3890 is a high performance dual step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phaselockable frequency of up to 850kHz. Power loss and noise due to the ESR of the input capacito.

LTC3890 Features

* n Wide VIN Range: 4V to 60V (65V Abs Max) n Low Operating IQ: 50µA (One Channel On) n Wide Output Voltage Range: 0.8V ≤ VOUT ≤ 24V n RSENSE or DCR Current Sensing n Out-of-Phase Controllers Reduce Required Input Capacitance and Power Supply Induced Noise n Phase-Lockable Frequency (75kHz to 850kHz)
