Linear Technology Corporation (Linear Technology Corporation) introduced the complete 3A DC / DC micro-module (uModule?) Control system LTM8033. The device in addition to built-in inductor, DC / DC converters and support circuitry, it also contains an EMI (electromagnetic interference) filter, so it is far better than the index in the EMI EN55022 Class B standards (which can be Login www.linear.com.cn / micromodule reference line report). The circuit is built in a small form 11.25mm x 15mm x 4.32mm closed plastic LGA (Land Grid Array) package, which weighs only 2.3g. LTM8033 in 3.6V to 36V wide input voltage range, and can range up to 3A to provide a stable 0.8V to 24V output voltage. If you need more than 3A of current, multiple LTM8033 devices in parallel in order to achieve current sharing. 
Because of simplicity, compactness and meets EN55022 standards, thereby LTM8033 to the operation of those requiring low noise applications, such as: medical equipment, avionics, communications, wireless systems and ultrasonic detectors. LTM8033 has a resistor can be used to select the switching frequency (adjustable range of 200kHz to 2.4GHz), enabling the designer to convert the operation under the VIN / VOUT than to improve efficiency. LTM8033 is rated for a temperature range of-40oC to 125oC and-55oC to 125oC. Approved the purchase price of the device one thousand pieces $ 11.95 each.
