LTC3829 - Single Output Synchronous Step-Down DC/DC Controller

General Description

The LTC®3829 is a high performance 3-phase single output synchronous step-down DC/DC switching controller that drives all N‑channel synchronous power MOSFET stages.

A constant frequency current mode architecture allows a phase-lockable frequency of up to 770kHz.

Key Features

  • n Optional Nonlinear Control for Fast Response n ±0.75%, 0.6V Reference Accuracy n PWM, Stage Shedding™ or Burst Mode® Operation n High Efficiency: Up to 95% n RSENSE or DCR Current Sensing n Programmable DCR Temperature Compensation n Phase-Lockable Fixed Frequency: 250kHz to 770kHz n True Remote Sense Differential Amplifier n Programmable Active Voltage Positioning (AVP) n Triple N-Channel MOSFET Synchronous Drive n Wide VIN Range: 4.5V to 38V Operation n VOUT Range: 0.6V to 5V without Diffamp.
