The LT3592 is an accurate, reliable LED driver that provides two LED current settings with a 10:1 ratio via a simple digital control pin. It is well suited for applications such as automotive brake light control.
The LT3592 is designed to simplify brightness control for LEDs in commercial, automotive, and industrial applications. It eliminates the need for external PWM signals by using a single digital control pin to switch between bright (up to 500mA) and dim (10% of bright current) modes via a simple resistor setting.
The device features rugged design elements suitable for tough environments, including an internal Schottky diode to reduce component count in series LED configurations. It includes protection circuits such as switch current limiting and catch diode current sense limiting to handle high input voltages up to 36V.
The device can handle a maximum input of 36V.
Bring the BRIGHT pin above 1.4V for high current, or below 0.3V for low current.
The frequency can be set anywhere between 400kHz and 2.2MHz.
