LM2853-1.8EVAL/NOPB

LM2853-1.8EVAL/NOPB is an evaluation board designed for use in off-line DC/DC or AC/DC switch-mode power supplies (SMPS). It enables users to build and evaluate their own power supply designs with the help of an easy to use user manual, software, as well as various hardware components like drive, diode bridge, and inductor.

Owing to efficient buck/boost topology, the evaluation board has a wide input voltage range of 4.5 V to 26 V. It offers fast transient response and near-perfect 50V output voltage regulation and excellent current limit. Also, the board has an on-board extended power supply with additional 5V output to power-up external parts. The board is also equipped with a thermistor and an over temperature sensing comparator.

When it comes to working principle, the DC/DC or AC/DC SMPS evaluation board transforms step-up input voltages to a regulated DC output voltage which is suitable for powering microprocessors and logic circuits. This is achieved by switching the power transistor at a certain frequency, which is defined by the clock oscillator.

The LM2853-1.8EVAL/NOPB evaluation board can be used in various applications such as in low power DC/DC converter, voltage regulators, power monitoring systems, and as a controller for AC/DC and DC/DC SMPS. It is a great choice for cost-sensitive applications such as consumer electronics and portable devices. In addition to all these features, the evaluation board is also RoHS compliant.

Overall, the LM2853-1.8EVAL/NOPB DC/DC or AC/DC SMPS evaluation board is an ideal platform to develop and evaluate various power supply designs. With its wide input voltage range, extended power supply, and excellent current limit, the board ensures efficient and reliable operation of the power supplies in various applications. It has become an essential tool for designing and debugging power supply units in cost effective way.
