IS31LT3954A Product details

Description

The IS31LT3954A 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.

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 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.
Robust f.
