The IW1209SA module is a family of DC/DC converters that span from 1.5 Amp to 11.5 Amp output current. These modules are suitable for applications such as industrial automation and control, telecom base stations, and LED lighting. They offer a wide range of features and performance including high efficiency, wide input voltage range, and a high power density.

The IW1209SA DC/DC converters employ advanced switching technology that results in excellent performance and reliability. At the heart of each module is a switching regulator that converts a wide input voltage range into a regulated output voltage. The IW1209SA module includes several protection features to protect the module from excessive power drain, overvoltage, short circuit, over temperature and other conditions that could cause damage or system shut down.

The IW1209SA module has a constant frequency PWM control and variable duty cycle to continuously regulate the output voltage. The output voltage is controlled by a voltage feedback loop that is tuned to maintain a set point relative to ground. This provides a very stable output voltage even when line or load conditions change. The output voltage can be easily adjusted by an internal resistor.

The IW1209SA module also offers stand alone output voltage trimming. This allows the user to adjust the output voltage via a potentiometer, without the need for an external trimming circuit. The module also includes output overvoltage protection that limits the output voltage to a safe level in the event of an output overload.

In addition, the IW1209SA module includes a programmable soft start feature that prevents inrush currents during turn-on and enables a gradual rise time to full output. This soft start feature is especially useful in applications that have large capacitive loads. The module also offers short-circuit and over temperature protection to help protect the module and system from damage due to fault conditions.

The IW1209SA module also includes several other features like local on/off control and remote on/off control. It also provides voltage sequencing and tracking capability that enables multiple outputs from a single module to be aligned and adjusted. The module is RoHS compliant and space saving, which make it ideal for embedded applications.

The IW1209SA module is well-suited for a wide range of applications including industrial automation and control, telecom base stations, LED lighting, portable medical equipment, and security systems. It is also a great choice for applications where shelf life, reliability, and power density are of utmost importance.
