具有串联 DIM FET 驱动器和故障标志的汽车类 N 沟道恒流 LED 控制器

The LM3421-Q1 and LM3423-Q1 family of devices are versatile high voltage N-channel MOSFET controllers for LED drivers. They can be easily configured in buck, boost, buck-boost and SEPIC topologies. This flexibility, along with an input voltage rating of 75 V, makes the these controllers ideal for il • AEC Qualified for Automotive Applications \n• Device Temperature Grade 0: −40°C ≤ TA ≤ 150°C (LM3421-Q0 and LM3423-Q0)\n• VIN Range From 4.5 V to 75 V\n• 2-Ω, 1-A Peak MOSFET Gate Driver\n• PWM and Analog Dimming\n• Programmable Switching Frequency\n• LED Output Status Flag (LM3423-Q1 and LM3423-;
