BD6112FVM-TR

The BD6112FVM-TR is a DC/DC switching regulator, a type of voltage regulator, from ROHM Semiconductor Corporation that offers high-speed, ultra-low Iq, low-noise, and low-distortion performance. The part works as a non-synchronous buck converter that utilizes high and low side complimentary MOSFETs and an optimized feedback loop controller optimized for high speed and accuracy.

The device is designed for the needs of portable devices, embedded devices, and automotive applications that require ultra-low Iq, high accuracy, and features that conserve space and simplify design. This part offers a single output voltage option that can be programmed as fixed or adjustable output voltage. Other features of the device include adjustable switching frequency, over-current protection, frequency Synchronization, and active damping.

The device can operate in a step-down, step-up, and inverting modes. In the inverting mode, the input voltage is connected to the output though the High side MOSFET and the output voltage is connected to the input through the low side FET. In the step-down (Buck) mode, the High side MOSFET is connected to the input voltage and the low side MOSFET is connected to the output. Finally, in the step-up (Boost) Mode, the High side is connected to the output and the low side is connected to the input voltage.

The BD6112FVM-TR utilizes an optimized switched mode power regulator that regulates the output voltage by accepting an input with a higher voltage than the output voltage, and then regulating it to the desired output voltage. When operating in the switching mode, the control IC monitors the output voltage and adjusts the duty cycle of the high side and low side MOSFETs to regulate the output voltage. The high/low side MOSFETs are then switched on and off in a pre-defined pattern in order to convert the input voltage to the desired output voltage.

The BD6112FVM-TR has two stages of protection. The first stage is an over-current protection (OCP) protection circuit, which is designed to protect the device and the load from over-current conditions. The second is a thermal shut-down protection (TSP) which is designed to act as a failsafe and can help protect the device from overheating.

The BD6112FVM-TR has a maximum output power of 12W, a core voltage of 3.3V, an operating temperature range from -25 to +85°C, and a noise suppression capability of 500nV/√Hz. It has a peak efficiency of 88%, and is available in an SO-8 package. The device is RoHS compliant and requires no external components for proper operation.

In conclusion, the BD6112FVM-TR is a DC/DC switching regulator from ROHM Semiconductor Corporation offering high-speed, ultra-low Iq, low-noise, and low-distortion performance. It is designed for the needs of portable devices, embedded devices, and automotive applications, and offers features such as adjustable switching frequency, over-current protection, frequency synchronization, and active damping. It utilizes an optimized switched mode power regulator to regulate the output voltage and has two stages of protection. The device is RoHS compliant and available in an SO-8 package, with a peak efficiency of 88%.
