DC826C-B

DC826C-B demonstration circuits features the LTC2951-2 respectively, which are low power, wide input voltage range, pushbutton on/off controllers. A pushbutton switch shorts the (active low)PB pin to ground which in turn sets the (active low)EN pin low. Shorting PB(active low) to ground a second time subsequently resets the (active low)EN pin high. The (active low)EN pin is used to connect to a DC/DC converter shutdown to control the turn on and off of the circuit, simulated with a green LED on the DC826C-B.
