DC-DC converters are used for transferring power between two isolated DC sources. The REC30-245.1S is a linear, step-up DC-DC converter which provides an efficient, cost effective solution for converting input power from low output to high output voltages. It is ideal for applications such as laptop computers, switch mode AC/DC power supplies, and automotive battery charging systems.

The REC30-245.1S employs an integrated switch isolated topology, providing an input to output isolation of up to 1000V DC. It has a wide input voltage range of 4.5V to 30V and an output voltage of up to 24V. It has built-in protection features such as Over-Voltage Protection and Over-Current Protection to regulate power and protect the load from fault conditions. The maximum output current is 1.2A and the maximum efficiency is 85%. It also has an easy to use adjust pin (AVP) to provide the user easy control and precise setting of output voltage.

The working principle of the REC30-245.1S is based on Pulse Width Modulation (PWM). The PWM converter controls the output voltage by modulating the duty cycle of the input signal. The duty cycle determines the amount of energy stored in the inductor and is regulated by an internal feedback circuit. The output voltage is determined by the turn ratio of the transformer and can be set by adjusting the duty cycle of the input signal. That is, the greater the duty cycle, the higher the output voltage. In order to maintain the correct output voltage, the feedback circuit adjusts the duty ratio according to the output voltage.

The REC30-245.1S also features a built-in Soft Start function, allowing the user to program the start-up voltage to prevent in-rush current from affecting the circuit and delaying the start-up time. It also has a wide operating temperature range of -40°C to 85°C and a high power density, making it suitable for a wide range of applications.

The REC30-245.1S is a highly efficient, cost-effective solution for stepping up the output voltage of low input voltages. It has built-in protection features and a wide operating temperature range, making it suitable for a wide range of applications such as laptop computers, switch mode AC/DC power supplies, and automotive battery charging systems.
