The XC9235A12CMR-G is a DC-DC switching regulator typically used in low-current, low-power applications. The device is part of a large family of products from the XC9235 series of voltage regulators.

The XC9235A12CMR-G is a buck (or step-down) converter, meaning the output voltage is lower than the input voltage, and it has current mode control. It is designed to regulate voltage in applications with DC input voltages ranging from 4.0 to 40 V and can provide output currents up to 1.25 A and output voltages as low as 1.25 V. The XC9235A12CMR-G is also equipped with current-limit circuitry that protects the device from overloads, short circuits, and over-temperatures.

In general, the XC9235A12CMR-G is used to convert a higher voltage DC supply into a lower one. This allows applications to run with a stable output voltage at a lower current draw than a linear regulator, resulting in increased efficiency. Additionally, the device can be used as a voltage selector and as a voltage-scale resistor for voltage monitoring as well.

The XC9235A12CMR-G is ideal for use in a variety of applications, including audio/visual equipment, cellular phones, telecom equipment, industrial instrumentation, and automotive electronics. Its main purposes in these applications include providing an adjustable output voltage and powering devices that require low-current, low-power operation.

The XC9235A12CMR-G is designed to ensure that the output voltage is constantly maintained and regulated regardless of the current level or load, making it an ideal choice for many low-power applications. To ensure this regulation, the device uses an internal switching transistor to control the output voltage.

The XC9235A12CMR-G’s internal switching transistor is driven by a pulse width modulator (PWM) that is triggered by voltage feedback from the output voltage and from an external resistor. This allows the device to adjust the Pulse Width Modulator’s frequency, thus regulating the output voltage. The external resistor is used to set the reference voltage, and the amount of voltage feedback from the output of the device is used to adjust the Pulse Width Modulator’s frequency, which in turn adjusts the output voltage.

The XC9235A12CMR-G also features Short Circuit Protection (SCP) to protect the device from overcurrent, open circuit, and over-temperature conditions. This is achieved by monitoring the current level through an internal current sense resistor and cutting the drive off when the current limit is exceeded. Additionally, the SCP can be disabled or enabled via an external signal.

In summary, the XC9235A12CMR-G is a DC-DC switching regulator designed for low-power, low-current applications. Its internal pulse width modulator and short circuit protection (SCP) ensure that the output voltage is constantly maintained and protected. Its adjustable output voltage and current-limit protection make it an ideal choice for a wide range of applications.
