Thông Tin Sản Phẩm
Tổng Quan Sản Phẩm
LTC3888-1 is a PMBus-compliant dual loop DC/DC synchronous step-down switching regulator controller with eight expandable phases. The controller uses constant frequency current mode architecture to provide excellent transient response and output regulation. Each PWM host is capable of producing output voltages from 0.3V to 3.45V with multiple phase configurations using DrMOS devices that provide an output current monitor. PMBus configuration and monitoring is supported by LTpowerPlay™ software. Application includes high current distributed power systems, servers, network and storage equipment.
- PMBus/I²C compliant serial interface, monitor voltage, current, temperature and faults
- Digitally program VOUT, margins, UV, OV, current limit, soft-start/stop and sequencing
- Programmable PWM Loop compensation, accurate PolyPhase® current sharing
- Internal EEPROM with ECC and fault logging, DrMOS output current monitor interface
- DrMOS temperature/fault bus interface, DrMOS gate drive supply monitor
- Load step emulation, internal or external PWM clock from 250KHz to 1MHz
- Operating range from 4.5 to 26.5V (TA=25°C, VIN=12V, VSENSEn+=1V0
- Typical operating current is 24mA (RUN0,1=0V, TA=25°C, VIN=12V)
- Gain error range from -4 to 4% (nominal gain at DAOUT: 1.00, TA=25°C)
- 52 lead plastic QFN package, temperature range from -40°C to 125°C
