MCP1663T-E/OT is part of Microchip\'s family of DC-DC switching regulators. It is suitable for general purpose applications, such as those found in automotive and industrial electronics, as well as those that require high reliability and low power consumption. The MCP1663T-E/OT uses a pulse width modulator (PWM) to control the switching frequency and thus regulate the output voltage.

The application field of MCP1663T-E/OT includes automotive electronics, industrial electronics, and other applications that require high reliability and low power consumption. It is well-suited for space-limited applications; the 4-pin space saving package makes it easier to find design space, allowing for more compact designs. Additionally, its wide input voltage range (4.5V to 28V) makes it a great choice for multiple-voltage input supplies. The MCP1663T-E’s allowed input voltage range can be reduced through external components, tailoring it to applications requiring lower input voltages.

MCP1663T-E/OT is ideal for space-limited applications. It offers excellent line, load and temperature regulation performance, enabling reliable voltage conversion in noise-sensitive operations. Its advanced PWM control includes cycle-by-cycle peak current limit, input undervoltage lockout and output overvoltage protection. Soft-start sequence prevents in-rush current at power-on. Additionally, peak current limit and overtemperature shutdown guarantee reliable operation under maximum load.

The working principle of MCP1663T-E/OT is based on pulse width modulation. In static mode, the internal charge pump controls the output voltage by adjusting the duty cycle of internal n-channel mosfets during load. When the load increases, the impedance drops, resulting in increased current draw from the output. The internal PWM then adjusts the voltage output by issuing more switching cycles to compensate for the increase in load.

The MCP1663T-E/OT provides accurate and stable voltage regulation over a wide temperature range, making it ideal for use in industrial and automotive applications. By utilizing a wide input and output voltage range, it is also suitable for multiple-voltage input supplies. The MCP1663T-E/OT is a reliable, cost-effective and easy-to-use solution for customers looking for a reliable and cost-effective DC-DC switching regulator.
