Overview

NCL30105 Constant Off Time PWM Current-Mode Controller for LED Applications The NCL30105 is a peak current controlled fixed off time controller designed for LED driver applications in which the LEDs are operated in deep Continuous Conduction Mode (CCM) without requiring slope compensation.

Featuring an adjustable off time generator, the controller can drive a MOSFET up to a 500 kHz switching frequency.

A dedicated dimming pin enables the use of a pulse−width modulated logic signal to dim the LEDs directly.

Key Features

  • robust protection features to detect switch overcurrent faults and to detect maximum on time events. Features.
