The MCP1631HVT-500E/ST is a power management integrated circuit (PMIC) designed to control and/or regulate DC/DC converters in a wide range of applications. This particular model is a current mode pulse width modulation (PWM) controller with integrated high side MOSFET, adaptive dead-time control, automatic power-up/power-down protection and foldback current limiting for protection against output overload conditions.

The device consists of two integrated circuits. The first is an internal high-side MOSFET, an on-board current-sense amplifier, a voltage reference and internal compensation circuitry. The second integrated circuit is composed of an adjustable voltage reference, a comparator and a PWM controller, all of which are used to generate and regulate the output voltage.

The output voltage of the device is controlled by adjusting the duty cycle of the current through the MOSFET. It is capable of delivering up to 500mA of output current and has a temperature range of -40°C to +125°C. The on-board current-sense amplifier can be used to measure the voltage across the load, allowing the device to sense the load current and regulate the output current accordingly.

The device includes adaptive dead-time control, which helps reduce overall power consumption of the system by being able to automatically adjust the “on” period of the PWM cycle. This reduces the overall peak-to-peak voltage across the MOSFET, reducing power dissipation and increasing efficiency of the system.

The MCP1631HVT-500E/ST also includes an automatic power-up/power-down feature which allows the device to turn off the output when the input voltage drops below a certain voltage. This prevents damage to the device due to over-current conditions and reduces overall power consumption. Additionally, it has a foldback current limiting feature that protects the device when the output load exceeds the maximum current rating of the device.

The MCP1631HVT-500E/ST is ideal for use in a wide range of DC/DC converter applications including automotive, industrial, consumer, portable and communications systems. It is capable of delivering high performance power conversion in a wide range of conditions and is designed to ensure the highest level of safety and reliability. It is an ideal choice for applications where high levels of accuracy and performance are needed.
