NCV30161中文资料Buck Regulator, Constant Current, for Driving High Power LEDs数据手册ONSEMI规格书

描述 Description

The NCV30161 is a hysteretic step−down, constant−current driver for high power LEDs in automotive applications. It is ideal for applications such as driver monitoring system.

The NCV30161 operates with an input voltage range from 6.3 V to 40 V. The hysteretic control gives good power supply rejection and fast response during load transients and PWM dimming to LED arrays of varying number and type.

A dedicated PWM input (DIM/EN) enables a wide range of pulsed dimming, and a high switching frequency allows the use of smaller external components minimizing space and cost. Protection features include resistor−programmed constant LED current, shorted LED protection, under−voltage and thermal shutdown. The NCL30161 is available in a DFN10 3 mm x 3 mm wettable flank package

简介

NCV30161属于集成电路（IC）的LED驱动器。由制造生产的NCV30161LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
