LM5012QDDARQ1 is a Texas Instruments LM5012-Q1 automotive buck converter in the 8-pin HSOIC PowerPAD package.
TI describes the LM5012-Q1 as an automotive, 6 V to 100 V input, 2.5 A non-synchronous buck converter with constant on-time control and ultra-low quiescent current.
It delivers up to 2.5 A over a 1.2 V to 95 V output range, draws 10 uA at no load, carries AEC-Q100 grade 1 qualification, and is specified from -40 °C to +150 °C junction.
It is used in automotive 48 V and 12 V rails, industrial supplies and battery-powered equipment that has to ride through load dumps.
Its advantage is the wide input range with constant on-time control: the converter runs from a 100 V rail and still responds to line and load steps without loop compensation components.
