STEVAL-0606YADJ [STMicroelectronics]

The STEVAL-0606YADJ product evaluation board is a step-down switching power supply based on the DCP0606Y regulator in a QFN11 2x3mm package.

The programmed switching frequency is 2.25 MHz 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 designed to deliver up to 6A continuous current.

The IC operates from 2.9 V to 6 V input voltage. 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.
