GENERAL DESCRIPTION
Selectable high switching frequency allows faster loop response and easy filtering with a low noise output. Soft-Start time can be programmed with an external capacitor, which sets the input current ramp rate. Current mode control and external compensation network make it easy and flexible to stabilize the system. Ordering Information LP6205S - □ □ □ F: Pb-Free Package Type B6: SOT23-6APPLICATIONS
