Description
The LT3570 is a buck and boost converter with internal power switches and LDO controller. Each converter is designed with a
The LT3570 features a programmable soft-start function that limits the feedback voltage during start-up helping prevent overshoot and limiting inrush current. The LDO controller is capable of delivering up to 10mA of base current to an external NPN transistor
