An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers. These devices are available in fixed output voltages of 3. V, V, V, and an adjustable output version. Efficient Pre−Regulator for Linear Regulators. On−Card Switching Regulators. Power Supply for Battery Chargers.

Negative Step−Up Converters. See detailed ordering and shipping information in the package dimensions section on page of this data sheet. A load with excellent line and load regulation. V, 5V, 12V, and an adjust- able output version.

Application Information section. The TPS series available from AVX, and the 593D series from Sprague are both surge current tested. Эти устройства доступны в версиях с фиксированными выходными напряжениями В, 5В,. Dropout Voltage: 2vdc minimum.

Принцип работы: управляемый ШИМ–сигналом мощный ключ внутри устройства посылает импульсы напряжения на индуктивность. В точке А x времени присутствует полное напряжение, и (1–x). There must be hundreds of thousands of these little switched mode regulator modules in China just waiting to. All circuits of this series are capable of driving a. Меньше нагревается если сравнивать с модулями на линейных стабилизаторах. Источник питания может применяться в широком спектре устройств.

Company, National Semiconductor Corporation. The higher the output voltage the higher the efficiency. A Step-Down Voltage Regulator. Arduino basics with Tinker Danica.

How to Make Learning More Fun? Ideal for battery operated projects. Sure must be a large stockpile of these parts sitting around in china. Thermal shutdown and current limit protection.

The rest of the components seem pretty standard and in fact the entire design seems to follow the example design given in the datasheet. The two exceptions being the inductor which is a 47uH instead of the . Typical Performance Characteristics (Circuit of Figure 1).
