Product Details

Demonstration circuit 1976A-A is a multioutput power supply with a pushbutton controller and I²C, featuring the LTC3676EUJ. The LTC3676EUJ has four synchronous buck regulators (1.5A x 2 and 2.5A x 2), an always-on LDO (25mA) and three 100mA LDO regulators. The 2.7V to 5.5V input voltage range of the LTC3676EUJ is ideal for single-cell Li-Ion/Polymer battery applications.
