Mouser Electronics, Inc., is now shipping the LTM8080 µModule® regulator from Analog Devices, Inc. The LTM8080 is a super low-noise, dual output DC/DC μModule regulator with patented silicon, layout and packaging innovations, specifically designed to power digital loads while reducing switching regulator noise for data converters, RF transmitters, FPGAs, op-amps, transceivers, medical scanners and more.
The Analog Devices LTM8080 µModule regulator, available from Mouser Electronics, features an integrated front-end, high efficiency, synchronous Silent Switcher® step-down regulator, supported by two separate low noise, low dropout (LDO) regulators. To further suppress switching noise, the LTM8080’s packaging integrates an EMI barrier shield to create exceptional low noise values of <1 µVRMS (10 Hz to 100 kHz), 2 nV/√Hz (10 kHz) spot noise, and 80 dB PSRR (power supply rejection ratio) (100 kHz). Compared to discrete solutions without an EMI shield, the LTM8080 reduces output ripple voltage by up to 70% for a simplified and quiet design.
Operating from 3.5 V up to 40 V input, the LTM8080 µModule Regulator has a built-in voltage tracking function that automatically sets VBUS to either 2.5 V nominal or 1 V higher than VOUT1, whichever is greater, to achieve superior noise performance and minimize power dissipation. The LTM8080 offers an intermediate power bus and dual output 0.5 A LDO regulators, which are adjustable to 3.3 V/0.5 A, and the package includes the controllers, power switches, inductors, and support components. The LTM8080 is packaged in a thermally enhanced, compact (9 mm × 6.25 mm × 3.32 mm) over-molded ball grid array (BGA) package, suitable for automated assembly by standard surface mount equipment, plus is RoHS compliant.
The LTM8080 µModule regulator is supported by the Analog Devices DC3071A evaluation board, available to order at Mouser Electronics. The DC3071A evaluation board provides an example application circuit based on the LTM8080 µModule, allowing rapid prototyping when incorporated into existing designs.
