Automotive 6 V - 6 A step-down converter. DC-DC buck converters
Text overview
The DCP0606Y is a high efficiency monolithic step-down synchronous switching regulator designed to deliver up to 6 A continuous current. The IC operates from 2.9 V to 6 V input voltage.
The DCP0606Y features low-resistance integrated N-channel MOSFETs and diode emulation working mode for optimum efficiency over all the loading range.
The integrated 0.6 V reference allows the regulation of output voltages with ± 1.5% accuracy over temperature variations. The switching frequency is externally adjustable between 1.8 MHz and 4 MHz.
The soft-start duration can be adjusted with an external capacitor or the same SS/TRK pin can be used for output voltage sequencing while the RST/PGOOD pin provides real-time information on the output voltage.
DCP0606Y is available in QFN 2x3 mm with 11 leads with wettable flanks.
