STMICROELECTRONICS STEVAL-0606YADJ Evaluation Board, DCP0606QTRY, Step-Down Converter

STEVAL-0606YADJ is an evaluation board for 3.3V/6A automotive step-down DC-DC converter based on the DCP0606Y regulator in a QFN11 2x3mm package. The programmed switching frequency is 2.25MHz with dithering, and it can be adjusted by applying an external clock on MODE/SIN pin or by changing the frequency programming resistor. The DCP0606Y is a high-efficiency monolithic step-down synchronous switching regulator that delivers up to 6A continuous current. DCP0606Y features low-resistance integrated N-channel MOSFETs and diode emulation working mode for optimum efficiency over all loading range. The integrated 0.6V reference allows the regulation of output voltages with ±1.5% accuracy over temperature variations. The switching frequency is externally adjustable between 1.8MHz and 4MHz. 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 RST/PGOOD pin provides real-time information on the output voltage.
