Product Overview
LTC3888 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. Programmable loop compensation and built-in load step emulation facilitate setting bandwidth based on input voltage and output load capacitance. PMBus commands allow read back of input voltage, output voltage and current, and operating status. It is used in application such as high current distributed power systems, servers, network and storage equipment etc.
- Monitor voltage, current, temperature and faults, expandable to >16 phases
- 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
- ±0.5% output voltage accuracy, VIN operating range is 4.5V to 26.5V
- IC operating current is 24mA typical at (RUN0,1 =TA = 25°C, VIN = 12V, 0V)
- Operating temperature is -40°C to 125°C, package style is 52-lead plastic QFN
