Product Summary

The LTC1628CG is a High Efficiency, 2-Phase Synchronous Step-Down Switching Regulator. It drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows adjustment of the frequency up to 300kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase.

Parametrics

LTC1628CG absolute maximum ratings: (1)Input Supply Voltage (VIN): 36V to –0.3V; (2)Top Side Driver Voltages: 42V to –0.3V; (3)Switch Voltage: 36V to –5V; (4)Peak Output Current <10ms: 3A; (5)INTVCC Peak Output Current: 50mA; (6)Operating Temperature Range: 0℃ to 85℃.

Features

LTC1628CG features: (1)Dual N-Channel MOSFET Synchronous Drive; (2)DC Programmed Fixed Frequency 150kHz to 300kHz; (3)Wide VIN Range: 3.5V to 36V Operation; (4)Very Low Dropout Operation: 99% Duty Cycle; (5)Adjustable Soft-Start Current Ramping; (6)Foldback Output Current Limiting; (7)Latched Short-Circuit Shutdown with Defeat Option.
