Beschreibung

This reference design describes the operation and performance of the NCV887103 automotive boost/SEPIC controller with a NVTFS5C478NL 40V single N−channel FET. The design demonstrates the NCV887103 controller capabilities as well as a complete designed for an automotive pre−regulator for broad range of applications. It is intended for the power supply designer to adopt the circuit directly into a typical system design, making only minimal component changes based on system requirements.The design is meant to be a complete solution, but it also provides access to key features of the NCV887103. These include peak current mode control with internal slope compensation, 1.2 V ±2% reference voltage, fixed frequency operation, wide input voltage range, input undervoltage lockout, internal soft−start, low IQ in sleep mode,cycle−by−cycle current limit protection, hiccup−mode overcurrent protection, hiccup−mode short−circuit protection and thermal shutdown.
