Low-Voltage DC DC Converters The Low-Vol DC to DC Converter include Point of Load DC to DC Converter (POL) and Low Voltage Difference Linear DC to DC Converter (LDO).The output voltage adjustable non-isolated DC to DC converter with BUCK circuit topology and pulse width modulation principle. The output sampling voltage is directly feedbacked to modulate the pulse width to achieve closed-loop control to meet the stability of the voltage output requirements. By changing the external resistance method to achieve the output voltage 0.8V-3.3V adjustable.. The series of products are made by thick-film hybrid integrated production process, metal sealed package.


The structure of series of LDO DC-DC Converter is the modular circuit. The series of products are made by thick-film hybrid integrated production process, metal sealed package.  .


The Low-vol DC-DC Converter is used in aerospace and high reliable electronic system.
