Description
LTC3850IGN-2#TRPBF Description
The LTC3850IGN-2#TRPBF is a high-performance dual synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 780kHz. Power loss and supply noise are minimized by operating the two controller output stages out of phase.

LTC3850IGN-2#TRPBF Features
Dual, 180° Phased Controllers Reduce Required Input Capacitance and Power Supply Induced Noise High Efficiency: Up to 95% RSENSE or DCR Current Sensing ±1% 0.8V Output Voltage Accuracy Phase-Lockable Fixed Frequency 250kHz to 780kHz Supports Pre-Biased Output Dual N-Channel MOSFET Synchronous Drive Wide VIN Range: 4V to 30V Operation Adjustable Soft-Start Current Ramping or Tracking Foldback Output Current Limiting Output Overvoltage Protection Power Good Output Voltage Monitor 28-Pin Narrow SSOP Package AEC-Q100 Qualified for Automotive Applications

LTC3850IGN-2#TRPBF Applications
Notebook and Palmtop Computers Portable Instruments Battery-Operated Digital Devices DC Power Distribution Systems
