A low-drift, on-chip reference and 14-bit ΔΣ A/D converter  
allow precise measurements of supply voltages, load  
currents or internal die temperature. Fault management  
allows ALERT to be asserted for configurable overvoltage  
and undervoltage fault conditions. Two voltage buffered,  
8-bit IDACs allow highly accurate programming of DC/DC  
converter output voltages. The IDACs can be configured  
to automatically servo the power supplies to the desired  
voltages using the ADC. The LTC2970-1 adds a tracking  
feature that can be used to turn multiple power supplies  
on or off in a controlled manner.
