Product Overview
LTC7883 is a quad, PolyPhase DC/DC synchronous step-down switching regulator controller with PMBus compliant serial interface. It uses a constant frequency, leading-edge modulation, voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.1V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. It can operate in parallel, supporting ideal phasor positioning for PolyPhase rails upto 8-phases. System configuration and monitoring is supported by the LTpowerPlay® software tool. This device serial interfaces can read back input voltage, output voltage and current, temperature and fault status. It is widely used in applications such as high current distributed power systems, servers, network and storage equipment, intelligent energy efficient power regulation etc.
- PMBus/I²C compliant serial interface, monitor voltage, current, temperature and faults
- Program voltage, soft-start/stop, sequencing, margining, AVP and UV/OV/OC limits
- ±0.5% output voltage error, accurate PolyPhase® current sharing
- Internal EEPROM with fault logging and ECC, IC supply voltage range from 3V to 13.2V
- Resistor or inductor DCR current sensing, power good output voltage monitor
- Supports start-up into a prebiased load, optional resistor programming for key parameter
- IC operating current is 32mA typ at (VCC = 5V, VSNSP = 1.8V)
- Error amplifier bandwidth is 30MHz typ (VCC = 5V, VSNSP = 1.8V)
- Operating temperature range from -40°C to 125°C
- Package style is 199-lead BGA
