z Simple High-efficiency step-down regulator z On-card switching regulators z Positive to negative converter PIN CONFIGURATION (1) TO220-5L (Top View) VVP3120 GENERAL DESCRIPTION
Due to reducing the number of external component, the board space can be saved easily. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. The VVP3120 series operates at a switching frequency of 52 KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
