L6732C application field and working principle

The L6732C is a DC-DC switching controller, designed and manufactured by STMicroelectronics. It is part of the ST PMIC-Voltage Regulators product family, and is widely used in integrated power supplies and other power management applications.

The L6732C solution is widely used in applications such as portable electronics, mobile handsets, power adapters, and smart home appliances. It can be used to provide regulated output voltage levels for various types of devices and circuits, such as LCDs, LEDs, and other integrated circuits.

Working principle of the L6732C

The L6732C DC-DC switching controller operates on the principle of pulse width modulation (PWM). This method of regulation is used in order to achieve accurate and stable output voltage.

The L6732C receives an input voltage from a power source, and then compares it against a reference voltage set by the user. It then adjusts the duty cycle of a PWM signal generated by the device in order to create the required output voltage.

This PWM output is then converted into an output voltage by the on-board power MOSFETs. The MOSFETs are responsible for controlling the amount of current supplied to the output, and thus the output voltage level.

Features of the L6732C

It offers a wide range of features, including: low quiescent current, current sensing, and over-current protection. It also supports a wide input voltage range of 4.5V to 17V, so it can be used in various types of applications.

In addition, the L6732C provides a low-voltage protection feature, which automatically shuts down the MOSFETs if the output voltage reaches a certain level. This helps to ensure the safety of the system by preventing the output voltage from overshooting the set limit.

Finally, the package size of the L6732C is very compact, making it ideal for use in space-constrained application environments.

Conclusion

The L6732C is a versatile DC-DC switching controller, designed and manufactured by STMicroelectronics for use in a variety of power management applications. It operates on the principle of pulse width modulation and is capable of providing accurate and stable output voltages for various types of devices and circuits.
