It may be synchronized to a clock or to separate NCV891930. Peak current mode control is employed for fast \u003c\/span\u003e\u003cspan\u003etransient response and tight regulation over wide input voltage and output load ranges. Feedback compensation is internal to the \u003c\/span\u003e\u003cspan\u003edevice, permitting design simplification. The NCV891930 is capable of converting from an automotive input voltage range of 3.5 V (4.5 \u003c\/span\u003e\u003cspan\u003eDuring startup) to 18 V at a constant base switching frequency above the sensitive AM band, eliminating the need for costly filters and \u003c\/span\u003e\u003cspan\u003eEMI countermeasures. The switching frequency folds back to 1 MHz for input voltages between 20 V up to 38 V (typical). Under load \u003c\/span\u003e\u003cspan\u003edump conditions up to 45 V the regulator shuts down. A high voltage bias regulator with automatic switchover to an external 5 V \u003c\/span\u003e\u003cspan\u003ebias supply is used for improved efficiency. Several protection features such as UVLO, current limit, short circuit protection, and \u003c\/span\u003e\u003cspan\u003ethermal shutdown are provided. High switching frequency produces low output voltage ripple even when using small inductor values and an all-\u003c\/span\u003e\u003cspan\u003eceramic output filter capacitor, forming a space-efficient switching solution.
