DC-DC converters are generic terms used to describe electronic conversion from one DC power level to another, such as stepping up or down a DC source level. DC-DC converters are used in numerous applications, from mobile phone chargers to computer space craft on-board power supplies. The QW015A0F1-S DC-DC converter provides a regulated DC output with a wide input voltage range of 8 to 32 volts, making it ideal for numerous applications.

The QW015A0F1-S DC-DC converter has a wide range of uses, such as industrial automation, medical equipment, instrumentation, building automation, and automotive applications. It is designed to provide up to 15 Watts of output power with reliable and efficient full wave power conversion. The QW015A0F1-S DC-DC converter is built with compact size, high reliability and excellent performance, making it suitable for a wide variety of power profiling applications.

The working principle of the QW015A0F1-S DC-DC converter is based on the featured Switched mode power supply (SMPS) topology. The SMPS topology is a power conversion technique used for converting electrical power from one form to another. The QW015A0F1-S DC-DC converter utilizes a full wave diodes and a circuit inductor, where the applied voltage is rectified into direct current and then filtered to obtain the AC ripple required to drive the MOSFETs, which are connected to the MOSFET drivers.

The MOSFETs are controlled by external circuit components called Control Logic Circuit (CLC), which controls the frequency and produce a pulse width modulation (PWM) signal that drives the MOSFETs. The MOSFET drivers constitute a state-of-the-art topology with a full synchronous rectifier, which performs power conversion from the one voltage level to the other. When the current reaches it’s peak value, the synchronous rectifier turns OFF the active power cycle for carrying the load current.

In order to keep the power stability, the synchronous rectifier also employs a Control Circuit to ensure that the current through the inductor is constant. The Control Circuit constantly monitors the power output and autonomously adjusts the frequency of the pulse width modulation (PWM) signal in order to maintain a fixed value of power output over a wide range of input voltage, temperature and loading conditions. In this way, the QW015A0F1-S DC-DC converter is able to provide a high level of energy efficiency and superior power conversion performance over a wide range of applications.
