DC2060A

DC2060A demonstration circuit is a single-rail circuit with an ideal diode and Hot Swap™ functionality provided by the LTC®4229, ideal diode and Hot Swap controller. The main components of this circuit are two series connected N-channel MOSFETs, a power sense resistor, few passive components, nine jumpers for selection of alternative operation modes, and four LEDs for visual indication of controller signals. One of the MOSFETs operates as an ideal diode and the other one as Hot Swap power switch. DC2060A facilitates evaluation of the LTC4229 in the different operation modes such as supply ramp-up, steady state, overcurrent faults, and power supply switchover. Power supply switchover mode can be realized when the LTC4229 controller operates in a prioritize set up or when a second ideal diode circuit is added. The DC2060A circuit is assembled to operate with a 12V supply and 10A maximum current load. The operating voltage can be easily readjusted for any voltage between 2.9V and 18V.

• Pads on key nodes are intended to be used as test points
• LTC4229 controller has two independent pins (SENSE+ and SENSE–) for the current sense signal
