Краткое описание:
Constant-Current 1.5A PWM Dimmable Buck Regulator LED Driver
Дополнительная информация
The IS32LT3952 is a DC-to-DC switching converter integrating an N-channel MOSFET for buck configuration. It operates from a wide input voltage of 4.5V to 38V, providing a constant output current up to 1.5A. It features true average output current control, spread spectrum for EMI optimization, and cycle-by-cycle current limiting. The device supports PWM dimming via the EN pin and includes robust fault protection against LED opens/shorts and thermal overload.
