The evaluation board NCV12711SSRGEVB is wide input range secondary-side-regulated flyback converter for automotive applications capable deliver up to 12W (12V/1A) on its output. The converter is built with the NCV12711 operated in current-mode control at 100 kHz. This control circuit offers many features to build an energy-efficient converter with all the needed protections like cycle-by-cycle current limit with a 250-mV sense voltage, over-current protection (OCP) and over-voltage protection (OVP) on the VCC pin. The controller drives an N-channel MOSFET as with any classical flyback converter at a user-adjustable switching frequency. The secondary side hosts a low-Vf diode for efficient rectification in continuous conduction mode (CCM). |
