PMIC - Voltage Regulators - DC DC Switching Regulators refer to a type of switch mode power supplies (SMPSs) that are commonly used to convert a source of direct current (DC) from one voltage level to another. Regulators of this type offer two main advantages: they are able to operate at higher output currents than linear regulators, and they are more efficient, meaning less energy is wasted as heat.

The BD7F200HFN-LBTR is an ideal example of a DC-DC switching regulator. It is specifically designed as a cost-effective solution for supplying power to low-power, low-voltage battery-powered electronic devices. It features an adjustable output voltage and stability, as well as a wide operating range.

The main application of BD7F200HFN-LBTR is to convert a battery’s lower voltage to a voltage that is compatible with a microcontroller’s (MCU) or other digital components’ requirements. Additionally, it can be used to supply a bridge-type motor-driver IC’s power supply terminal, as well as to power a wide range of other small digital devices.

The BD7F200HFN-LBTR features a low drop-out regulator with adjustable output and an operating current of up to 150mA, an input voltage of 1.8V-6V and an output voltage adjustable from 0.8V to 4.5V. Its standby current is typically 10μA, and its start-up time is 2μs. It is also resistant to over-temperature and short-circuit protection.

The operating principle of BD7F200HFN-LBTR is based on a controlling circuit integrated into the device. This circuit monitors the output voltage and adjusts the input level by switching off the power transistors when the output voltage rises above or below the desired voltage. This process is repeated at regular intervals and allows for a steady output voltage.

The BD7F200HFN-LBTR is also equipped with an under-voltage lockout (UVLO) that ensures that the output voltage is not lower than the desired level. When the input voltage drops below the specified level, the output is shut down and the device enters a low-power state. This protection feature makes the device more reliable and ensures a longer lifetime.

In addition, the device features an integrated frequency compensation circuit that eliminates the need for external components to stabilize the output voltage. This simplifies the design of the power supply and reduces component costs. The device also features thermal protection that shuts down the output when the temperature exceeds a certain threshold.

Overall, the BD7F200HFN-LBTR is a highly efficient, cost-effective solution for powering low-voltage, low-power portable devices. It is versatile, reliable, and offers a wide input and output voltage range, as well as thermal protection. Given its advantages and features, the BD7F200HFN-LBTR is ideal for a wide range of battery-powered applications.
