DC DC converters are devices that regulate the output voltage of a DC power source by changing the ratio between input voltage and output voltage. The SUS61205BP is a DC DC converter from Analog Devices that provides a regulated output of +10V from a +1.2V to +1.45V input. The output voltage is adjustable between +0.2V to +12V with no external components required. This device is ideal for applications requiring low input voltage and high output voltage, such as mobile phones, medical and communication systems.

SUS61205BP has integrated power MOSFETS that provide up to 500mA of continuous current at the output for improved power conversion efficiency. It has a switching frequency of 400KHz which allows it to achieve a maximum power conversion efficiency of 95% and a minimum power conversion efficiency of 65%. The device features built-in under voltage protection that senses the input voltage and will shut down the device at lower voltages, extending battery life.

The SUS61205BP operates on a two-step buck-boost topology that uses a feedback loop for precise regulation of the output voltage. The feedback loop is composed of two internal voltage reference regulators, one is set to regulate the output at the desired voltage, and the other is set to regulate the input voltage. This topology is able to provide a constant output voltage, regardless of changes in input voltage, load current, or temperature.

The SUS61205BP features a wide range of protection features, such as input under-voltage lock-out, thermal shutdown, and output current limit protection. It is also protected from short-circuiting and open-circuiting of the input and output. The device is equipped with a status flag that will indicate when the input voltage is below the lock-out threshold, or if over-temperature conditions are present. It also features an enable/disable pin which can be used to turn off the converter.

The SUS61205BP is an efficient and reliable DC DC converter that can provide up to 500mA of continuous current from a lower input voltage. Its high power conversion efficiency and integrated protection features make it well-suited for a wide range of applications, such as mobile phones, medical systems, and communication systems. It can be easily configured using external components and can be controlled with an enabled/disable pin.
