LT3685EDD#TRPBF Description

Short technical summary and product information.

The LT3685EDD#TRPBF is a monolithic step-down switching regulator designed by Linear Technology (now Analog Devices). It accepts input voltages up to 36V, with overvoltage protection capable of withstanding transients up to 60V. This regulator can deliver up to 2A of output current.

Key electrical specifications include an adjustable switching frequency ranging from 200kHz to 2.4MHz, allowing for the use of small external components. It features a low shutdown current of less than 1µA and a saturating switch with 0.25Ω on-resistance for high efficiency. The feedback reference voltage is 0.79V, and the output voltage can be programmed from 0.79V to 20V.

The LT3685EDD#TRPBF includes a power good flag that signals when the output voltage reaches 89% of the programmed level, and it supports soft-start capability for controlled output voltage ramp-up. It is available in compact, thermally enhanced packages: a 10-pin MSOP and a 3mm x 3mm DFN.

Applications for this regulator include automotive battery regulation, set-top boxes, distributed supply regulation, and industrial power supplies. Its wide input range and high switching frequency make it suitable for space-constrained designs requiring low output ripple.
