Non-isolated buck and buck/boost converter demo board

1. Introduction

WARNING

Lethal voltage and fire ignition hazard

The non-insulated high voltages that are present when operating this product, constitute a

risk of electric shock, personal injury, death and/or ignition of fire.

This product is intended for evaluation purposes only. It shall be operated in a designated test

area by personnel qualified according to local requirements and labor laws to work with

non-insulated mains voltages and high-voltage circuits. This product shall never be operated

unattended.

This user manual describes a +12 V AC/DC buck and

12

V AC/DC non-isolated

buck/boost-mode SMPS that can be used to supply up to 2.5 W into a load.

The switch mode converter operates at a maximum frequency of around 50 kHz.

Overcurrent and short-circuit protection are built in. Under no-load conditions, the power

consumption of this converter is in the range of 10 mW. EMI filtering and (optional) surge

voltage protection using TVS diodes is implemented in this circuit.

This application is a general purpose non-isolated SMPS.

In applications where triacs are driven in the third quadrant (such as white goods

applications), the negative output voltage with respect to Neutral or Phase makes

buck/boost converters particularly interesting.

The optional surge protection makes it suitable for use in environments where serious

voltage transients can occur. The absolute maximum RMS mains input voltage is

280 V (AC).

1.1 Features and benefits

•

Compatible with Universal Mains

Inrush current limitation

EMI filtering to meet EMC requirements of EN55022

Surge input voltage protection

2. Safety Warning

The demo board is powered by AC mains voltage. Avoid touching the board when power

is applied. An isolated housing is obligatory when used in uncontrolled, non-laboratory

environments.
