Краткое описание:
Constant-Current 1.5A PWM Dimmable Buck Regulator LED Driver
Дополнительная информация
The IS31LT3952 is a DC-to-DC switching converter that integrates an N-channel MOSFET to operate in a buck configuration. It supports a wide input voltage range from 4.5V to 38V and provide a constant output current up to 1.5A. The device features spread spectrum operation to optimize EMI performance and utilizes a cycle-by-cycle controlled on-time method for fast transient response and true average output current control.
