MCP1825T-0802E/DC

The MCP1825T-0802E/DC is a DC to DC step-up converter voltage regulator, belonging to PMIC (Power Management IC)’s Linear Voltage Regulators (LVRs) family. As a Low-Voltage/Light-Load DC/DC Converter, it features high current output, low voltage quality and wide operating temperature range. It is ideally suited for automotive and industrial applications that need an energy efficient regulator with versatile functionality.

The MCP1825T-0802E/DC is designed to convert and regulate the voltage of any DC input voltage source. It uses a low Pin-Count Boost DC-to-DC regulator to step-up the input voltage from the input supply to generate the regulated output voltage. This voltage regulator circuit works by using a inductor-diode charge pump circuit to generate the required output voltage by generating a current flow across the output pins. When the current flows across the output pins, the output voltage is regulated by the output voltage control loop. This voltage output control loop is made up of feedback resistors which are connected to the output pins, an error amplifier and a pulse width modulation generator circuit to ensure that the output voltage is maintained at the set output voltage level. The output voltage can be further adjusted by adjusting the feedback resistors.

In order to make it energy efficient, a number of features are incorporated in the device such as low quiescent current and very low standby power. The quiescent current is typically 20μA, and the standby power is 1mW. The input supply voltage range is 2.5V to 10V, while the output voltage range is adjustable from 2.5V to 8V. The MCP1825T-0802E/DC also includes a wide range of protection features such as an overvoltage protection circuit, a thermal shutdown circuit, an undervoltage lockout circuit, and a low voltage protection circuit. Additionally, the device also includes a soft-start circuit which helps to reduce the inrush current.

In summary, the MCP1825T-0802E/DC is an energy efficient voltage regulator suitable for a variety of automotive and industrial applications. It features high current output, low voltage quality, wide operating temperature range and a number of protection features. With its step-up converter design and variety of versatile features, the MCP1825T-0802E/DC is a reliable and efficient DC to DC step-up converter voltage regulator.
