NCV890131MWTXG

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-36В (Vin), 3.3В/1.2A выход, 2.2МГц.

The NCV890131MWTXG is a fixed-frequency monolithic buck Switching Regulator intended for battery-connected applications that must operate with up to a 36V input supply. The regulator is suitable for systems with low noise and small form factor requirements often encountered in automotive driver information system. It is capable of converting the typical 4.5 to 18V automotive input voltage range to outputs as low as 3.3V at a constant switching frequency above the sensitive AM band, eliminating the need for filters and EMI countermeasures. Two pins are provided to synchronize switching to a clock or to another NCV890131. It also provides several protection features expected in automotive power supply systems such as current limit, short-circuit protection and thermal shutdown. In addition, the high switching frequency produces low-output voltage ripple even when using small inductor values and an all-ceramic output filter capacitor-forming a space-efficient switching regulator solution.
