DC-DC converters are devices designed to efficiently convert a DC input voltage into a DC output voltage. REC10-4815D/H2/M is a switching buck-boost converter designed for space-constrained mobile and battery-powered applications. It offers wide input voltage range, up to 95V, and output current up to 2A, with high efficiency and low component cost. With an internal switch, it eliminates the need for large external components.

The REC10-4815D/H2/M consists of two input terminals, four control and programming pins, one output terminal and two power good output pins. The input port of the device is provided with two input terminals, VDD and VSS. VDD is connected to the input voltage and VSS is connected to ground. The four control pins include two mode control pins, MOD0 and MOD1, a chip enable pin, EN, and a power good monitor pin, PG.

The REC10-4815D/H2/M operates in three different modes depending on the voltage of the input voltage: buck, boost, and buck-boost. In buck mode, the input voltage is greater than the output voltage. In boost mode, the input voltage is less than the output voltage. In buck-boost mode, the input voltage is higher and lower than the output voltage at different points in time. The mode of operation is determined by setting the MOD0 and MOD1 pins. If MOD0 and MOD1 are both high, the device operates in buck mode. If MOD0 is low and MOD1 is high, the device operates in buck-boost mode. Finally, if both MOD0 and MOD1 are low, the device operates in boost mode.

The REC10-4815D/H2/M has a wide input voltage range that can accommodate a voltage range from 3.3V to 95V. It has internal shunt-based power limiting for overcurrent protection and thermal shutoff protection for the switch. It also has overvoltage and undervoltage protection for both input and output voltages.

The REC10-4815D/H2/M has a wide application field. It is suitable for automotive applications due to its wide voltage range, high efficiency, and low component cost. It is also suitable for wearable electronics, consumer electronics, and mobile power supplies due to its small size, low noise, and high efficiency. It is also used in industrial applications, such as industrial controllers, motor controls, server power supplies, and LED lighting, due to its wide voltage range and high power efficiency.

The REC10-4815D/H2/M works on the principle of current-mode control. In current-mode control, the output current is compared with a reference current to generate a control signal for the switching element. This control signal determines the amount of current flowing through the switch and, consequently, the amount of power delivered to the load. This helps ensure efficient operation and prevents overcurrent and short-circuit conditions.

The REC10-4815D/H2/M is a versatile and efficient DC-DC converter designed for space-constrained mobile and battery-powered applications. With an internal switch, it eliminates the need for large external components. It has wide input voltage range, up to 95V, and output current up to 2A, with high efficiency and low component cost. Its wide application field and efficient operation come from its use of current-mode control.
