DC DC converters are one of the most widely used components in the modern electronics world. RKE-1205S/H is a newly designed converter, providing versatile output options while delivering high performance in a variety of applications. This article will discuss the features of the RKE-1205S/H and its application fields, and also explain its working principle.

The RKE-1205S/H provides two step-down voltage outputs, 55 V and 15 V. The 55 V output can be used for two extreme applications in the same design, including high voltage Battery Management System (BMS) and low voltage FPGA and DSP subsystems. What\'s more, the 15 V output is suitable for all Power over Ethernet (PoE) applications.

Utilizing advanced power conversion and isolated SMD technology, the RKE-1205S/H is capable of converting a wide input voltage from 4V to 24V to the corresponding outputs. Its high power density up to 10 Watts in SIP package make it perfect for applications where space is of the utmost importance. Furthermore, it integrate over-temperature protection, short-circuit protection and current limiting protection, which enhance its anti-jamming capability.

RKE-1205S/H belongs to switching DC DC converter, consisting of an input circuit, an output circuit and a control circuit. It works in two switch operation mode, Flyback and Boost+Flyback, which is controlled by the microprocessor (MCU). The input circuit of RKE-1205S/H contains an inductor, a diode and a capacitor. When the MCU provide the control signal, the switch will be turned on. Then energy is stored in the inductor, which increases the current and magnetic field. Afterward, the switch is turned off and the energy is converted to the output voltage. In order to optimize the power transfer, the capacitor smooth the current and adjust the output voltage. The output voltage is regulated by the MCU.

RKE-1205S/H can be used in a wide array of applications, including automotive, medical instrument, ultra-wideband radar substrate, etc. Due to its versatile output options, reliable performance and excellent thermal control, RKE-1205S/H has been used by many leading companies for their products. Thus, RKE-1205S/H DC DC converter is the best choice for applications with small size and high power requirements.
