| Manufacturer | Lumissil |
| Description | The IS32LT3953B is a DC-to-DC switching converter that integrates an N-channel MOSFET to operate in a buck configuration. The device can operate from a wide input voltage between 4.5V and 38V and provides a constant current of up to 3A for driving a single LED or multiple series connected LEDs. The external resistor, RISET, is used to set a constant LED outp. |
| Features |
Wide input voltage supply from 4.5V to 38V - Withstand 40V load dump True average output current control 3A maximum output over operating temperature range Cycle-by-cycle current limit Integrated high-side MOSFET switch Dimming via analog input, direct logic input or power supply voltage Internal control loop compensation Under-voltage lockout (UVLO) and thermal shutdown protection 2μA low power shutdown Spread spectrum to optimize EMI Internal linear regulator output (VDD) to bias the external circuit Robust fault protection: - Pin-to-GND short - Component open/short f. |
