DC-DC converter programmable via SMBus/I2C

20 June 2001 Power Electronics / Power Management

Linear Technology's LTC1699 is a variable resistor divider with +0,35% accuracy, and software programmed through a 2-wire SMBus or I2C interface. It provides the flexibility to digitally set the output voltage of a DC-DC converter without modifying the circuit board. The IC simplifies the implementation of a voltage regulator module; voltage margining and power supply sequencing, for use with CPUs, DSPs, FPGA, and ASICs. Two digital codes may be written and stored into the LTC1699's registers via a SMBus or I2C interface. A code is chosen to set the output voltage of a 0,8 V referenced DC-DC converter using the digital SEL pin. The device incorporates a special write-protect safeguard that prevents misprogramming of the output voltage due to bus conflicts or errors.
