MCP1650R-E/MS

The MCP1650R-E/MS is a DC-DC buck controller that allows you to easily implement a cost-effective and high-efficiency design. It Ideallly targeting charge pumps, buck converters, and other DC-DC power converters, the MCP1650R-E/MS provides a high level of versatility and functionality.

The device can be configured in linear or switching mode buck converters, with pre-programmed default operating frequency. It includes a wide operating temperature range, allowing the buck converter to operate from -40C to 85C. The device also features a 1.8V to 6V input voltage range and adjustable PWM frequency from 400kHz to 3.2MHz.

In addition to buck converter operation, the MCP1650R-E/S provides a wide range of features such as adjustable rise and fall times, adjustable output current limit, and adjustable over current protection. The device also supports over voltage protection with adjustable hysteresis, and programmable power-up/power-down sequencing.

The MCP1650R-E/MS is a single-phase synchronous buck converter. It consists of an external coil, inductor, and a MOSFET switch. When an input voltage is applied, the MOSFET switch is turned on, allowing current to flow from the input voltage to the inductor. As the current through the inductor increases, a magnetic field is created, storing energy. When the MOSFET switch is turned off, the stored energy is released to the output.

When operating in switching mode, an internal PWM signal is generated by the MCP1650R-E/MS. This signal is used to control the on/off times of the MOSFET switch. The frequency of the PWM signal can be adjusted from 400kHz to 3.2MHz with a 0.5% accuracy. The duty cycle of the PWM signal can also be adjusted to provide constant output current.

The MCP1650R-E/MS can be used in a variety of applications. It is suitable for battery charging, high-efficiency step-down converters, LED drivers, and more. The device is also ideal for polishing high-current power rails, such as those in LED drivers orPoE solutions. The adjustable frequency, duty cycle and current limits make it ideal for applications where high efficiency is desired.

In summary, the MCP1650R-E/MS is an ideal single-phase synchronous buck converter for applications requiring efficiency, flexibility, and a wide input voltage range. The adjustable frequency, duty cycle and current limit allow the user to tailor the design for the desired output. The device’s wide operating temperature range makes it suitable for use in applications subject to extreme temperature conditions.
