UC3842BVDR2G Integrated Circuits (ICs)

UC3842BVDR2G is a Pulse Width Modulation (PWM) Control Circuit, which falls into the PMIC - Voltage Regulators - DC DC Switching Controllers category. It is primarily designed to be used as a voltage regulator to protect sensitive electronic devices. The device can both sense and control the output voltage of DC-DC power converters.

This device is unique in that it is capable of both voltage regulation and voltage limiting. It has a wide range of applications, including but not limited to, battery powered mobile devices, computer peripherals, and charge pumps. The control voltage range is 0V to 7.5V, making it suitable for a variety of applications.

UC3842BVDR2G application field
UC3842BVDR2G has a wide application field, such as Battery Charging. The device can be used to protect the battery from potential overcharging, as the voltage regulator can be configured to limit the charge voltage to a predetermined level. This ensures the battery is charged safely and not damaged by overcharging.

Another application is DC-DC Power Converters. The UC3842BVDR2G can provide precise control over the output voltage of a DC-DC power converter. The device can be used both to regulate the output voltage and to limit it, depending on the application. This can be used to ensure that the output voltage remains within the desired range, while simultaneously protecting the load from potential damage due to overvoltage.

Finally, the UC3842BVDR2G can also be used to protect sensitive electronic devices from potential overvoltages. The voltage regulator can be configured to limit the voltage to a predetermined level, to ensure the device does not suffer any potential damage from overvoltage.

UC3842BVDR2G working principle
The UC3842BVDR2G works by sensing and controlling the output voltage of the DC-DC converter. It uses a reference voltage, which is compared with the output voltage, to monitor and adjust the output. This reference voltage can be adjusted to the desired level, which is useful for voltage regulation or voltage limiting.

The device utilizes a Pulse Width Modulation (PWM) control circuit to regulate the output voltage. It employs an internal error amplifier to compare the reference voltage to the output voltage. If the output voltage is higher than the reference voltage, a signal is sent to reduce the width of the PWM control signal. This reduces the amount of current supplied to the load, thus reducing the output voltage.

Similarly, if the output voltage is lower than the reference voltage, a signal is sent to increase the width of the PWM control signal. This increases the amount of current supplied to the load, thus increasing the output voltage. This allows the device to precisely control the output voltage, and maintain it within a desired range.

The UC3842BVDR2G is a highly capable device, which is suitable for a wide range of applications. Its PWM control circuit and adjustable reference voltage make it ideal for a variety of applications, including battery charging, DC-DC converters, and protecting sensitive electronic devices.
