I am using the ltc3118 in a battery-powered device. Because of that, I want to use it in burst mode. I used the typical application note from the datasheet. IN1: 18V wall socket, IN2: Battery pack 12V, OUT: 5V. With almost no load the voltage is quite stable and I can see the burst characteristics on the scope. As soon as I want to get higher output currents the output voltage drops to 0-1V.
Is there any problem with the specifications or the circuit from the datasheet?
