DC DC Converters are used to convert DC voltage/current from one level to another. The DKM10B-05 is a type of DC DC Converter designed for applications such as industrial, automotive, and telecommunications. It is a 5W isolated DC DC converter in a SIP module of 10.2mm x 9.7mm x 6.5mm.The DKM10B-05 is an isolated step up converter with a wide input voltage range of 3.4V to 30V. Its fixed switching frequency is 225KHz with high efficiency up to 91%. Its output voltage is adjustable between 4.2V to 30V with ±3% accuracy and no-load consumption lower than 40uA. The DKM10B-05 has over current protection and can work under harsh conditions with its wide temperature range from -40℃ to +85℃. It has a high power density, up to 6.5W/cm³, enabling applications with space limitation and high power demands.The DKM10B-05 starts with an input voltage of 3.4V and boosts it up to an adjustable 4.2V to 30V. Its internal high-frequency oscillator generates two-level curves, which are shifted in respect to each other for a balanced transformer’s magnetic flux. During the start-up, the transformer’s magnetic flux is smooth, avoid the output voltage overshoot. The DKM10B-05 has low power loss and high efficiency due to the use of a PWM controller and an thermistor circuit to provide over current protection on output side.The input side of the DKM10B-05 is protected by an OVLO circuit with OVP and UVP and the output by OCP. It also supports remote on/off control and power good indicator. Its reliability is improved by a torque reinforced case and its environmental protection by air ventilation slots.To sum up, the DKM10B-05 is an effective and reliable DC DC Converter with wide input voltage range, adjustable output, high efficiency, and, since it is in a SIP module, a very low power density and small size. Its ability to work under harsh environment and the protection circuits make it suitable for a large variety of industrial, automotive, or telecommunications applications.
