Product Specifications

Technical details and manufacturing context for DC-DC Converter

Definition
A DC-DC converter is an electronic device or circuit that converts a source of direct current (DC) from one voltage level to another. It is a type of power converter that uses high-frequency switching and energy storage components like inductors and capacitors to efficiently change the voltage level while maintaining DC characteristics. These converters are essential in applications where the available DC power source voltage does not match the required load voltage. This directory entry covers a specific DC-DC converter model with an input voltage range of 9–36 V DC, a regulated output of 5 V DC, and a maximum continuous output current of 2 A. The converter achieves an efficiency of at least 90% at specified load conditions and operates at a switching frequency of 300 kHz. It is designed for an ambient operating temperature range of -40°C to 85°C. Key performance specifications include line regulation of ±0.5%, load regulation of ±1.0%, and output ripple and noise of 50 mV peak-to-peak (measured with a 20 MHz bandwidth). The converter provides input-to-output isolation of 1500 V DC (for 1 minute) and includes overcurrent, overvoltage, and overtemperature protection. It comes in a standard DIP package with dimensions of 25.4 mm x 25.4 mm x 10.2 mm and weighs approximately 15 g. The device is constructed using semiconductor silicon, copper, ferrite core, aluminum, and epoxy resin. This product is intended for use in computer, electronic, and optical product manufacturing. For any specific application, verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
DC-DC converters operate by rapidly switching a semiconductor device (typically a MOSFET) on and off at high frequency. During the on-state, energy is stored in an inductor or transformer. During the off-state, this stored energy is transferred to the output through a diode or synchronous switch. By controlling the duty cycle (ratio of on-time to switching period) through pulse-width modulation (PWM), the average output voltage can be regulated to the desired level. Feedback circuits monitor the output voltage and adjust the duty cycle to maintain stable output despite input voltage variations and load changes.
