LINEAR TECHNOLOGY LTC3882EUJ-1#PBF 芯片, 控制器, 同步降压, 1.25MHZ, QFN-40
The is a dual output PolyPhase step down DC to DC voltage mode controller with digital power system management in 40 pin QFN package. This synchronous step down switching regulator controller uses a constant frequency and leading edge modulation voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.5V to 5.25V using a wide range of 3.3V compatible power stages including power blocks, DrMOS or discrete FET drivers. Up to four LTC3882-1 devices can operate in parallel for 2, 3, 4, 6 or 8 phase operation. System configuration and monitoring is supported by LTpowerPlay software tool. The LTC3882-1 serial interface can read back input voltage, output voltage, output current, temperature and fault status. Most operating parameters can be set via the digital interface or stored in internal EEPROM for use at power-up.
