IC revision1.0

Description

The STEVAL-0608Y1V8 product evaluation board is a step-down switching power supply based on the DCP0608Y regulator in a QFN11 2x3 mm 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 DCP0608Y is a high efficiency monolithic step-down synchronous switching regulator designed to deliver up to 8 A continuous current.The IC operates from 2.9 to 6 V input voltage. The DCP0608Y 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 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.
