Linear Technology has expanded its family of ultra low noise DC/DC µModule regulators with the LTM8032, an electromagnetic compliant DC/DC regulator system-in-package.
It includes the inductor, switching DC/DC controller, power switches, filters and all support components in a 9 x 15 x 2.82 mm land grid array (LGA) package.
The device has been tested by an independent EMI test laboratory and is compliant with the radiated emissions requirements of EN55022 class B. The switching frequency can be adjusted from 200 kHz to 2.4 MHz with a resistor or can be synchronised to an external clock.
The device operates from a wide input voltage range of 3.6 to 36 and regulates an output voltage from 0.8 to 10 at up to 2 A.
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, minimising the input quiescent current.
