R1270S-A/K

3A 34V输入带PLL同步功能的PWM/VFM降压DC/DC转换器（汽车级）;

The R1270 Series are 34V input (Absolute maximum rating: 36V), CMOS-based PWM/VFM step-down DC/DC converters capable of outputting the maximum 3A* current. The R1270 is selectable from two control types - PWM control or PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. The R1270 includes a soft start circuit, a fold-back protection circuit and a latch protection circuit (only A Version). By simply using an inductor, resistors, and capacitors as external components, a high-efficiency step-down DC/DC converter can be easily configured. The R1270 can be synchronized externally by PLL.\n\n*) This is an approximate value, because output current depending on conditions and external parts.\n\n\n\n\n\n\n\n\n\n
