LTC3646EMSE#TRPBF Description

Short technical summary and product information.

The LTC3646EMSE#TRPBF from Analog Devices is a synchronous step-down DC/DC converter designed for high voltage applications. It offers a wide input voltage range of 4.0V to 40V and can deliver up to 1A of output current. This converter utilizes internal high-side and synchronous power FETs, drawing a low 140µA of DC supply current in Burst Mode operation at no load.

 

Key features include an adjustable output voltage, a switching frequency adjustable from 200kHz to 3MHz, and ±1% accurate reference voltage. The device supports both Burst Mode operation for high efficiency across a broad range of load currents and forced continuous mode for ripple-sensitive applications. Its patented controlled on-time architecture and 0.6V reference voltage enable large step-down ratios without output overvoltage risk.

 

The LTC3646EMSE#TRPBF is housed in a 16-lead MSOP-EP (Exposed Pad) package, suitable for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ). This robust part is ideal for point-of-load power supplies, intermediate bus power, and automotive applications.

 

Applications include point of load power supplies, intermediate bus power, and automotive applications. The device's combination of high efficiency, integrated power switches, and low quiescent current makes it a versatile solution for various power management needs.
