Краткое описание:
38V White LED Driver with PWM Brightness Control
Дополнительная информация
The TPS61161A is a boost converter with a 40-V rated integrated switch FET designed to drive LEDs in series. It operates at a 600-kHz fixed switching frequency and supports an input voltage range of 2.7 V to 18 V. The device features a 200-mV feedback voltage regulated with ±2% accuracy and uses a PWM interface for brightness control where the duty cycle determines the feedback reference voltage. It includes integrated 38-V open LED protection and a built-in soft start to prevent inrush current.
