Dual 3A PSU on a Chip

Intersil have introduced a single chip just 9 x 6.5 mm which contains just about all the control features (including the output stages) needed to build a dual 0.8 to 5 V power supply with 3 A per channel output capability. The ISL8203M can also supply 6 A in current sharing operation. The ISL8203M is an integrated step-down power module optimized for generating low output voltages down to 0.8V.  The input s ...
