® RTQ2104-QA 36VIN, 3A, High Efficiency, 2.1MHz, Synchronous StepDown Converter with Low Quiescent Current General Description The RTQ2104 is a 3A, high-efficiency, current mode synchronous step-down converter which is optimized for automotive applications. The device operates with input voltages from 3V to 36V and is protected from load dump transients up to 42V, eases input surge protection design. The device can program the output voltage between 0.8V to VIN. The low quiescent current design with the integrated low RDS(ON) power MOSFETs achieves high efficiency over the wide load range. The peak current mode control with simple internal compensation allows the use of small inductors and results in fast transient response and good loop stability.
