Analog Devices Inc. LTM8083 Buck-Boost μModule® Regulators

Analog Devices Inc. LTM8083 Buck-Boost μModule® Regulators are designed to regulate output voltages with seamless low-noise transitions between operation regions. These regulators feature adjustable output current limit, output current monitoring, integrated three-terminal capacitors, and spread spectrum for excellent EMI performance. The LTM8083 regulators operate from 3V to 36V input voltage range, 1V to 36V output voltage range, and 300kHz to 2MHz switching frequency range. These regulators are packaged in thermally enhanced, compact over-molded Ball Grid Array (BGA) packages that are suitable for automated assembly by standard surface mount equipment. The LTM8083 regulators are used in applications such as battery-operated devices, industrial control, solar-powered voltage regulator, solar-powered battery charging, and test and measurement equipment.
