Original Press Release:

EN55022 Class B Noise Compliant 3A DC/DC µModule Regulator Operates from 3.6V to 36V Input

MILPITAS, CA - Linear Technology Corporation introduces the LTM8033, a complete 3A DC/DC µModule® regulator system. In addition to the device's onboard inductor, DC/DC converter and supporting circuitry, it includes an EMI (electromagnetic interference) filter, making it compliant with EN55022 Class B by a wide margin (see online report at www.linear.com/micromodule). The circuitry is housed in a small 11.25mm x 15mm x 4.32mm enclosed plastic LGA (land grid array) package and weighs only 2.3g. The LTM8033 operates from a wide input voltage range of 3.6V to 36V and can provide a regulated output voltage ranging from 0.8V to 24V at up to 3A. If more than 3A is required, multiple LTM8033 devices can be paralleled for current sharing.

Simplicity, compactness and EN55022 compliance allows the LTM8033 to be used in applications that require low noise operation such as medical equipment, avionics systems, communication wireless systems and ultrasonic detectors. The LTM8033 has a resistor-selectable switching frequency adjustable from 200kHz to 2.4MHz, enabling the designer to improve efficiency according to the VIN-to-VOUT ratio of the conversion. The LTM8033 is rated for operation from -40°C to 125°C and -55°C to 125°C. 1,000-piece pricing starts at $11.95 each. For more information, visit http://www.linear.com/8033.
