The IR3094MPBF is a monolithic integrated switch mode circuit controller specifically designed to provide high voltage outputs synchronised to a control signal. It is typically used in finite element converters, used to convert a given high voltage, such as a automotive battery, to a regulated output of a specific voltage and current. It consists of a dedicated high voltage power MOSFET designed for very low on resistance, a high performance analogue voltage regulator with integrated buffer, a PFM/PWM internal modulator, a set of functional and protection features, positive and negative current limit and over voltage protection.

The power MOSFET can be switched by the control signal to switch the battery voltage in the FET array, then the internal modulator regulates both switching frequency and power loss. It is capable of adjustable output voltage range between 2.5 and 30V. The output voltage can be set via the Voltage Regulation pin and monitored with the Voltage Feedback pin.

The positive and negative current limits are defined as the upper and lower current values when the power MOSFET is conducting. The internal voltage regulator then provides an output voltage by controlling the switching frequency. It features a PFM/PWM internal modulator and a protection loop which shuts down the switching cycle when load current is too high or when the output voltage is too high or too low.

The IR3094MPBF offers many additional protections, such as over temperature protection, Soft start, Power on reset, as well as a variety of other features to ensure reliable operation. In addition, it offers full configurability of the switching frequency, output voltage, duty cycle, over voltage protection, and current limit. This makes the IR3094MPBF a great choice for stationary and mobile applications.

In short, the IR3094MPBF is a highly configurable and feature-packed switch mode DC/DC controller, ideally suited for applications where high voltage and high current capabilities are required. Thanks to its wide operating temperature range and excellent safety and protection features, the IR3094MPBF is an ideal choice for many power management applications.
