3 Descriptions of HNSX5S Series Point of Load DC/DC Converters (POL)

This device is a high-reliability, outputhigh voltage DC/DC Converter. Buck circuit topology and the principle of pulse width modulation are used in devices. The output voltage will regulate the pulse width of the controller by direct sampling feedback to ensure the stable output voltage. Output voltage can be 0.9V～1.3V adjustable by the variation of externally connected resistor .The series of devices use thick-film hybrid integrated process and metal sealed enclosure package. The design and manufacturing process of HNSX5S Series converters are in compliance with MIL-PRF-38534 and detailed specifications
