详细介绍
The FP5208, FP5208A and FP5208B are boost topology switching regulator for wide operating voltage applications. They provide built-in gate driver pin for driving external N-MOSFET. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage. They have programmable soft start time set by external capacitors. FP5208 and FP5208B have programmable frequency set by external resistors. FP5208A and FP5208B have programmable current detection and over current protection set by external resistors.
The FP5208A and FP5208B are available in the small footprint DFN-12L package to fit in space-saving PCB layout for application fields.
