Working Principle

The IR3628MTRPBF uses a buck-boost converter topology to provide the required output voltage. This topology ensures that the device can maintain a wide range of input/output voltage conditions. The working principle of the device is as follows:

1. At a given input voltage, the Buck-Boost converter topology of the IR3628MTRPBF ensures that the required output voltage is maintained.
2. The IR3628MTRPBF uses a variable frequency, peak current-mode control algorithm to maintain the output voltage. The algorithm adjusts the switches’ on-off times and frequency to maintain the desired output voltage.
3. The IR3628MTRPBF also features an over-voltage and under-voltage protection circuit, which protects the device from damage in the event of an output voltage over- or under-voltage condition.
4. The IR3628MTRPBF also features a programmable current limit circuit, which allows the user to limit the amount of current drawn from the power source.
5. The IR3628MTRPBF\'s remote sensing capability allows the user to adjust the output voltage at its load end to ensure that the desired accuracy is maintained.
6. The IR3628MTRPBF also features an active current limit in its shutdown mode, which limits the amount of current drawn from the power source, even in the event of an output voltage fault.
7. The IR3628MTRPBF\'s digital ON/OFF control feature allows the user to control the device via an external control signal.

The IR3628MTRPBF also features a thermal shutdown protection circuit, which is triggered if the die temperature of the device rises above a predetermined limit. This protection circuit prevents the device from becoming damaged due to excessive heat.
