Buck LED Driver with 4.5V~38V Input and 3A Average Output Current
Дополнительная информация
The IS31LT3953B is a DC-to-DC switching converter that integrates an N-channel MOSFET to operate in a buck configuration. The device operates with a wide input voltage range from 4.5V to 38V and provides a constant output current of up to 3A. It features a controlled on-time method for fast transient response and true average output current operation. The switching frequency is dithered for spread spectrum performance to optimize EMI. It includes support for both Analog and PWM dimming and is available in an AEC-Q100 qualified version for automotive applications.
