The LT8618JDDB#TRPBF from Analog Devices is a compact, high-speed synchronous monolithic step-down switching regulator designed to deliver up to 100 mA of output current with high efficiency, even at a constant frequency.

If you’re working on industrial sensors, Industrial Internet of Things systems, 4mA to 20mA current loops, flow meters, automotive housekeeping supplies, or compact power management designs, the LT8618JDDB#TRPBF is a dependable choice.

This device is listed as a Subscriber Line Interface Concept, or SLIC, telecom IC in a PG-VQFN-48 package. It supports IOM-2 and PCM interfaces and is designed for surface-mount assembly, making it suitable for compact voice communication hardware.

Here’s what you’re getting with this part:

**Key Features of the LT8618JDDB#TRPBF**

**High Efficiency Synchronous Operation**

The LT8618JDDB#TRPBF is designed for high-efficiency synchronous step-down operation, helping reduce power loss in compact electronic systems. It can achieve more than 90% efficiency at 30 mA, making it suitable for designs where efficient power conversion is important.

**Wide Input Voltage Range**

The LT8618JDDB#TRPBF supports a 3.4V to 60V operating input range, with a 65V maximum transient rating. This makes the part useful in applications requiring reliable voltage regulation under varying input conditions.

**100mA Output Current Capability**

The LT8618JDDB#TRPBF can deliver up to 100mA to the output, making it suitable for low-power rails, housekeeping supplies, sensor systems, and compact embedded designs.

**Ultralow Quiescent Current**

In Burst Mode operation, the LT8618JDDB#TRPBF consumes very low quiescent current, with the datasheet listing less than 2.5 µA while regulating 48 VIN to 3.3 VOUT. This supports efficient operation in light-load or standby conditions.

**Adjustable Output Regulation**

As an adjustable variant, the LT8618JDDB#TRPBF offers engineers flexibility in setting output voltage requirements across different system designs.

**Fast Minimum Switch-On Time**

The device features a fast minimum switch-on time of 35 ns, enabling efficient high-frequency operation and helping maintain regulation across a wide input voltage range.

**Adjustable Switching Frequency**

The LT8618JDDB#TRPBF supports an adjustable switching frequency from 200kHz to 2.2 MHz, giving engineers flexibility in balancing efficiency, component size, and noise considerations.

**Compact 10-Lead DFN Package**

The LT8618JDDB#TRPBF is supplied in a compact 10-lead 3mm × 2mm DFN package, making it well suited to space-constrained PCB designs where efficient power conversion is required.

**Power Good Flag and Thermal Protection**

The device includes a PG flag that signals when the output voltage is within regulation, along with thermal shutdown protection for added reliability under fault or high-temperature conditions.

## **Applications of the ** **LT8618JDDB#TRPBF**

The LT8618JDDB#TRPBF is typically used in:

- Industrial sensors
