Linear Technology Corporation (Linear Technology), a manufacturer of standard linear integrated circuits, has introduced a new DC/DC regulator system-in-package, LTM8032, to its family of ultralow noise DC/DC µModule regulators. The new LTM8032 is an electromagnetic compliant (EMC). The new LTM8032 incorporates the inductor, switching DC/DC controller, power switches, filters and all support components in a 9mm x 15mm x 2.82mm land grid array (LGA) package.
The LTM8032 has been tested by an independent EMI test laboratory and is compliant with the radiated emissions requirements of EN55022 class B. The switching frequency of the LTM8032 can be adjusted from 200 kHz to 2.4MHz with a resistor or can be synchronized to an external clock. The device operates from a wide input voltage range of 3.6V to 36V and regulates an output voltage from 0.8V to 10V at up to 2A. Applications for the LTM8032 include converting and regulating automotive battery voltage, distributed power supply, and high voltage industrial and avionics systems.
The LTM8032 weighs only 1.2g and is tested for two temperature ranges satisfying -40ºC to 125ºC industrial and -55ºC to 125ºC military specifications. For higher output power, two or more LTM8032s can be paralleled for current sharing. To improve efficiency at light loads, the device automatically activates Burst Mode® operation. This keeps the output capacitor charged to the proper voltage with single cycle bursts of current followed by sleep periods, minimizing the input quiescent current. The LTM8032 is priced at $10.95 each in 1,000-piece quantities.
