I'm having trouble with a circuit that converts a low DC voltage (e.g. from a wall adapter) to a +/- 30V regulated supply. The circuit has a boost regulator (LT8330) followed by a dual supply inverting charge pump (LTC3260). Here's the circuit:
The spice simulation works as designed, however in reality not so much. The regulator (LT8330) circuit worked on the PCB, however the LTC3260 burnt immediately after connecting the supply. From the simulation there's some pretty large current spike at the Vin of the charge pump during start up which may be the problem. It's not clear to me from the datasheet how much this component can handle though.
Any help would be appreciated. Thanks.
