regulator controller optimized for 5V input to a digitally
programmable 1.3V-3.5V output. The internal 5-bit DAC
programs the output voltage from 1.3V to 2.05V in 50mV
increments and from 2.1V to 3.5V in 100mV increments. The
precision internal reference and an internal feedback system
provide an output accuracy of В±1.5% at room temperature
and typically В±2% over temperature, load current and line
voltage shifts. The LTC1753 uses a synchronous switching
architecture with two external N-channel output devices, …
