VPOL5A-5-SMT-TR Power Supplies - Board Mount

DC-DC converters are used in many different types of applications including Power Supplies, PCs and automotive systems. They are typically used to convert electrical energy from one form to another, either from AC to DC or from DC to AC. They are also used to regulate the voltages in an electrical system. VPOL5A-5-SMT-TR is one such DC-DC converter which offers a range of features and benefits.This converter has a nominal input voltage range of 5.0V to 24V and can be operated either in isolated or non-isolated modes. It features an operating temperature range of -40°C to 85°C, a max efficiency of 92% and a switch frequency of up to 300kHz. It is also designed with high EMI and RFI suppression capabilities and has a very low output ripple.The VPOL5A-5-SMT-TR adopts a synchronous rectification topology, which helps to enhance efficiency without generating extra heat. The internal MOSFETs in the converter can handle a continuous 8A output current and a peak value of up to 12A. The converter also features an internal short circuit protection to prevent over current, over temperature and over voltage conditions to protect the device. The working principle of the VPOL5A-5-SMT-TR is quite simple. It consists of two parts, the primary and the secondary. The primary part of the converter takes the input voltage and converts it to an AC voltage. The AC voltage is then rectified and filtered to become a DC voltage of desired output which can be adjusted via the on-board trim potentiometer. The secondary part of the converter is used to provide regulation of the output voltage. This is done by using pulse width modulation to reduce the input voltage to the desired output voltage. The duty cycle of the pulses is determined by the on-board trim potentiometer which is adjusted for a particular application. In conclusion, the VPOL5A-5-SMT-TR is a highly efficient DC-DC converter which is well suited for applications where high-efficiency, low-noise and excellent thermal performance are required. It is easy to use and offers a range of benefits including wide input voltage range, high efficiency, low ripple and high EMI/RFI suppression.
