제품 개요
LTC3874 is a dual PolyPhase® current mode synchronous step-down controller. It enables high current, multi-phase applications when paired with a companion host controller by extending the phase count. It employs a unique architecture that enhances the signal-to-noise ratio of the current sense signal, allowing the use of sub-milliohm DC resistance power inductors to maximize efficiency while reducing switching jitter. Its peak current mode architecture allows for accurate phase to phase current sharing even for dynamic loads. It is widely used in applications such as high current distributed power systems, telecom, datacom, and storage systems, intelligent energy efficient power regulation etc.
- Accurate phase-to-phase current sharing
- Phase-lockable fixed frequency from 250KHz to 1MHz
- Immediate response to host IC's fault, upto 12 phase operation
- Wide VIN range from 4.5V to 38V
- Proprietary current mode control loop
- Programmable CCM/DCM operation
- Programmable phase shift control, dual N-channel MOSFET gate drivers
- VOUT range is upto 3.5V (LOWDCR pin = INTVCC), upto 5.5V (LOWDCR pin = OV)
- Shutdown current is 1.8mA typ at (TA = 25°C, VIN = 12V)
- Operating temperature range from -40°C to 125°C, package style is 28-lead plastic QFN
