Linear Technology Corporation announces the LTC3815, a high efficiency 6A monolithic synchronous step-down DC/DC converter with an I2C-based PMBus interface for digital power system management (PSM). The LTC3815’s simplified and intuitive PMBus “Lite” command set makes it simple to use. The digital interface provides programming and read back of voltage, current, temperature and faults; all supported by LTpowerPlay™ software. This interface allows the output voltage to be margined over a ±25% range with 0.1% resolution. The default output voltage is set with a single external resistor and will power up to this voltage with or without the serial interface.
