The LT3592EMSE#TRPBF from Analog Devices is a fixed-frequency step-down DC/DC converter that functions as a constant-current source, making it ideal for driving high-current LEDs. It operates with a wide input voltage range from 3.6V to 36V and offers an adjustable switching frequency between 400kHz and 2.2MHz.
This LED driver supports adjustable LED currents of 50mA and 500mA, with a 10:1 dimming capability using an external signal. The device incorporates features like shorted and open LED protection, internal switch current sense, and catch diode current sense to prevent runaway conditions at high input voltages. Its current mode PWM architecture ensures fast transient response and cycle-by-cycle current limiting, while thermal shutdown provides additional protection.
The LT3592EMSE#TRPBF is available in a small, thermally enhanced 10-lead DFN (2mm x 3mm) and MSOP-10 packages, saving space and cost. Its high switching frequency allows for the use of small inductors and ceramic capacitors, contributing to a compact solution. This makes it suitable for applications such as automotive signal lighting and industrial lighting, as well as constant-current and constant-voltage power supplies.
