DC DC ConvertersDC DC converters are electronic circuits which convert direct current (DC) from one voltage level to another. The QW020A0G1Z is a rugged, high efficiency, low profile wide input voltage range DC DC converter with a power output of 8A. It is built on a high SIP (Single In-line Package) technology which offers inrush current limiting and excellent thermal and electrical performance.FeaturesThe features of the QW020A0G1Z are as follows:• Wide 2:1 input voltage range: 6.5V to 13V and 18V to 36V• Output voltage range: 3.3V to 5.0V• 8A output current• Efficiency of up to 89%• Low standby power consumption• Low profile package height of only 14mm• Operational temperature range from -40°C to 85°C• Output over-voltage protection• Short-circuit protection• Inrush current limitWorking PrincipleThe QW020A0G1Z DC DC Converter converts the incoming direct current from one voltage level to another. It works on the principle of pulse width modulation (PWM) technology. PWM is a technique used to generate a square waveform with a specific duty cycle. This PWM signal is then used to control the power switch circuitry of the converter and the switch is turned on and off in a synchronized manner. As the switch is turned on and off, it creates a saw-tooth output voltage waveform whose amplitude and frequency are determined by the PWM duty cycle. This saw-tooth output voltage waveform is then smoothed by a filter circuit resulting in a desired output voltage.Application FieldThe QW020A0G1Z can be used in a wide range of applications including:• Industrial control systems• Telecommunications systems• Computers and peripherals• Automotive applications• Industrial and instrumentation equipment• Voltage regulation• Battery chargingConclusionThe QW020A0G1Z is a rugged, low profile, high efficiency DC DC converter with a power output of 8A. It is built on a high SIP technology for excellent thermal and electrical performance and is suitable for a wide range of applications. This converter is well-suited for providing a regulated output voltage in the absence of an AC power source and for power conversion applications in Telecom, Industrial, Automotive and Instrumentation sectors.
