42VIN, 3A, Asynchronous Step-Down Converter with Low Quiescent Current
General Description
The RTQ2949A is a 3A, high-efficiency, peak current mode control asynchronous step-down converter. The device operates with input voltages from 4V to 42V which is optimized for automotive applications. The device can program the output voltage between 0.8V to VIN and is protected from load dump transients up to 65V which eases input surge protection design. The low quiescent current design with the integrated low RDS(ON) of high-side MOSFET achieves high efficiency over the wide load range. The peak current mode control with simple external pensation allows the use of small...
