The MCP1630-E/MC is a Voltage Regulators and DC DC Switching Controllers in the PMIC market. It is a full integrated PWM system solution for DC DC buck and boost applications. It is widely used in a variety of applications such as consumer electronics, cellular/mobile phones, hard disk drives and telecommunication equipment.

The MCP1630-E/MC includes the control built-in high voltage DC-DC switching controllers and MOSFET gate drivers. It also includes a modulated PWM (pulse width modulation) control circuit that allows precise digital control of the switching frequency and duty cycle. This high accuracy digital feedback control allows precise control of output voltage and current, making it suitable for battery charge applications.

The MCP1630-E/MC has a low output voltage of 1.5V and a maximum output voltage of 36V, with an adjustable output voltage range of up to 5V or 3V. It has adjustable switching frequencies up to 1MHz and is capable of providing up to 8A output current. It also has very low ripple voltage and is capable of providing very low temperature rise even with high output current.

The MCP1630-E/MC works by generating modulated PWM (pulse width modulation) control signals that are sent to the gate of the MOSFET (metal-oxide-semiconductor field-effect transistor). The PWM control signal switches the gate of the MOSFET according to the duty cycle commanded by the control IC, allowing precise digital control of the switching frequency and output voltage/current. This provides a closed-loop feedback mechanism to ensure the desired output voltage or current is maintained.

The MCP1630-E/MC provides two control loop settings, one for maintaining an output voltage and the other for maintaining an output current. It features over-voltage and over-current protection and provides a soft start function that prevents the output voltage from rising suddenly at the start-up. It is also equipped with an Automatic Power Save Mode that detects low load conditions and reduces the switching frequency to save power.

The MCP1630-E/MC is a highly integrated voltage regulator and DC DC switching controller suitable for a variety of applications. It features easy to use modulated PWM control, low output voltage and ripple voltage, and adjustable switching frequency up to 1MHz. It has over-voltage and over-current protection, and provides excellent thermal protection with an onboard thermal sensor. Its Automatic Power Save Mode detects low load conditions and reduces the switching frequency to save power, making it suitable for battery charge applications.
