- Integrated overvoltage protection (OVP)
- Integrated reversed leakage protection (RLP) with adjustable threshold
- Integrated thermal shutdown (TSD) with adjustable threshold
- Integrated UVLO / EN pin
Working Principle of the RT7236GCP
The RT7236GCP is a DC DC buck-boost step-down converter. It has a high-side MOSFET that dissipates most of the switching losses, which allows for improved efficiency. The output of the switch is connected to an inductor, which stores the energy in its magnetic field. This stored energy is then released to the output capacitor at the same rate that it was taken from the input, thus providing a regulated output voltage.
The circuit has two main operating modes: continuous conduction mode (CCM), and discontinuous conduction mode (DCM). In CCM, the inductor current and input voltage is always above the threshold, so the switch is always conducting and the current is continuous. In DCM, the inductor current is below the threshold and the switch is off for a short period of time to prevent the inductor from saturating. The RT7236GCP automatically switches between these two modes depending on the load requirements.
The RT7236GCP offers a wide range of features including programmable switching frequency, integrated over-current protection (OCP), integrated over-voltage protection (OVP), integrated reversed leakage protection (RLP) with adjustable threshold, and an integrated UVLO/EN pin.
Advantages of the RT7236GCP
- Compact Design: The RT7236GCP is a compact unit with a footprint of 3.0 x 3.2mm, making it suitable for low profile, space-saving applications.
- High Efficiency: The integrated high-side MOSFET dissipates switching loss, allowing for improved efficiency.
- Programmable Switching Frequency: The user can adjust the switching frequency, allowing for flexibility and customization.
- Integrated Protection Features: The RT7236GCP features protection features such as OCP, OVP, and RLP with adjustable thresholds.
Conclusion
The RT7236GCP is a versatile DC DC switching regulator that can be used in a wide range of applications. It offers a compact design with a footprint of 3.0 x 3.2mm, high efficiency due to its integrated high-side MOSFET, and protection features such as OCP, OVP, and RLP with adjustable thresholds. The user can also adjust the switching frequency, allowing for further customization to meet the application requirements.
