Introduction to DC1737A

The DC1737A is an evaluation board for a non-isolated, synchronous buck converter. It is designed and manufactured by Linear Technology and can be used as a DC/DC & AC/DC (Off-Line) SMPS. The board consists of the LTC3408 switching controller, low gate charge MOSFETS, power inductor, bootstrap diode and support components. This combination enables the board to provide a 120W output at 90% or greater efficiency.

Application Field and Working Principle

The DC1737A board is suitable for a wide range of applications. It works well as an intermediate bus converter for DC/DC & AC/DC (Off-Line) SMPS designs. The board is also suitable for applications in which the output needs to be accurately regulated (e.g. medical equipment or communication systems).

The DC1737A board features an efficient synchronous buck topology. The LTC3408 switching controller drives two N-channel MOSFETS which switch at an operating frequency of 500 kHz. This allows the board to transform input voltages up to 56V to a precisely regulated output voltage. The board has several other features, including current-mode control, an internal soft-start, cycle-by-cycle current limit protection and thermal overload protection.

The DC1737A evaluation board allows users to quickly and reliably prototype their own designs. A set of tuning headers enables the user to adjust the switching frequency, soft-start time and operating current limits, without the need for external circuits. The board can also be interfaced to a PC via the LTC USBLink software, providing control and monitoring of the board in real time.

Conclusion

This article has provided an overview of the DC1737A evaluation board. This board is suitable for DC/DC & AC/DC (Off-Line) SMPS designs, as well as other applications which require a precisely regulated output. The board features an efficient synchronous buck topology, allowing users to quickly prototype their own designs and make tuning adjustments. The board can also be interfaced to a PC, providing further flexibility.
