VE-B3N-IX

DC/DC converters are essential components of many portable battery operated electronic circuits, and the VE-B3N-IX is one of them. It is a highly efficient, low quiescent current, step-up charge pump DC/DC converter with wide input voltage range from 0.5V up to 5.5V and output voltage range from 3V up to 17V. A key feature that distinguishes it from other similar products is its built-in low-cost voltage doubler, which simplifies the circuit design and provides extra protection and stability.

The VE-B3N-IX is ideal for portable applications which require higher voltages from low voltage inputs. It can be used with two-cell AA or AAA battery and generate a maximum of 17V output. In addition, the frequency is internally set and it can be adjusted using an external resistor. The input current in standby mode is typically less than 0.3mA and the maximum output current is about 150mA, which is suitable for most small electronic systems.

The VE-B3N-IX has a wide input voltage range and is ideal for portable applications. It has two selectable output modes: normal mode and fast mode. In normal mode, the output voltage is regulated with 1.25% accuracy, while in fast mode, it can be regulated with a 0.25% accuracy. It also features overvoltage protection and thermal overload protection.

The VE-B3N-IX works on the principle of a charge pump and a transformer. On the input side, two switching MOSFETs switch between the input voltage and ground potential. The output voltage is determined by the selected output mode and the applied gate voltage. The voltage doubler built inside the IC takes the input voltage and doubles it before the transformer. The transformer then amplifies the voltage and passes it to the output.

The VE-B3N-IX can operate at frequencies from 1kHz up to 20kHz, which is ideal for high efficiency operation. It also has a low electromagnetic interference (EMI) level and is easily integrated into many electronics systems. In addition, it has a wide operating temperature range of -40°C to +85°C, making it suitable for use in harsh environments.

The VE-B3N-IX is designed for applications where high voltage input is not available or is expensive. It is a highly efficient and cost effective solution for many portable electronics applications. Its small size, low quiescent current, low EMI level, and wide range of operating temperatures make it a great choice for mobile, battery operated equipment.
