产品概述
LTC3887 is a dual, PolyPhase DC/DC synchronous step-down switching regulator controller with an I²C-based PMBus compliant serial interface. This controller uses a constant frequency, current mode architecture that is supported by LTpowerPlay® a software development tool with graphical user interface (GUI). Switching frequency, channel phasing, output voltage, and device address can be programmed using external configuration resistors. Additionally, parameters can be set via the digital interface or stored in EEPROM. Voltage, current, internal/external temperature and fault status can be read back through the bus interface. It has integrated gate drivers. It is widely used in application such as high current distributed power systems, telecom, datacom and storage systems, intelligent energy efficient power regulation etc.
- Telemetry read back includes VIN, IIN, VOUT, IOUT, temperature, duty cycle and faults
- ±0.5% output voltage accuracy over temperature
- Integrated 16bit ADC, internal EEPROM and fault logging with ECC
- VOUT range is 0.5V to 5.5V (VOUT0, VOUT1)
- Integrated N-channel MOSFET gate drivers
- Minimum On-time is 45ns typ at (TA = 25°C, VIN = 12V)
- Wide VIN range is 4.5V to 24V
- Analog current mode control loop, remote differential sense for PolyPhase® applications
- Accurate polyphase current sharing for upto six phases
- Operating junction temperature is -40°C to 125°C, package style is 40-lead plastic QFN
