REC3-243.3SRW/H2/C/SMD-R

DC-DC converters are components that perform signal conversion between two distinct voltage levels, sometimes referred to as a down converter or up converter. The REC3-243.3SRW/H2/C/SMD-R is a DC-DC converter that is particularly applicable for use in applications that require robust performance in an extremely small form factor. In order to understand the application field and working principle of this specific converter, its features and components must first be taken into account.

The REC3-243.3SRW/H2/C/SMD-R is a 12-volt DC to 24-volt DC converter. This device is capable of a 100% duty cycle, operating input currents up to 3A, and providing output currents up to 1.2A. Furthermore, it features a wide input voltage range of 6 to 36 VDC, a wide -40°F to +140°F temperature range, and a low standby current of less than 16mA, all contained within an ultra-small weight of 12.6 grams. These features make it ideal for applications with limited space or extreme environmental conditions.

This DC-DC converter also features an array of external components including an input capacitor, MOSFETs, and a feedback network. The input capacitor works to filter out input ripple, while the MOSFETs are responsible for serving as the power switches. The feedback network is used to monitor and regulate the output voltage of the converter. Additionally, the converter employs a PWM (Pulse-Width Modulation) circuit design which helps to ensure a robust output voltage.

The working principle of the REC3-243.3SRW/H2/C/SMD-R is as follows. The input voltage is first filtered by the input capacitor and is then provided to the PWM circuit. The PWM circuit generates a rectangular pulse signal integrated with various levels of duty cycle. This pulse signal is then amplified by the MOSFETs and sent to the output. The transformer in the device then changes the output voltage according to the pulse duty cycle and provides the output current that is regulated by the feedback network.

In summary, the REC3-243.3SRW/H2/C/SMD-R is an ultra-small DC-DC converter that is ideal for applications with limited space or extreme environmental conditions. It uses an array of components including an input capacitor, MOSFETs, and a feedback network to ensure robust performance. Additionally, it employs a PWM circuit design for increased stability. This device is applicable for use as a 12-volt DC to 24-volt DC converter and is capable of operating input currents up to 3A, and providing output currents up to 1.2A.
