The LTM8060 is quad 40VIN, 3A step-down Silent Switcher μModule® regulator. The Silent Switcher architecture minimizes EMI while delivering high efficiency at frequencies up to 3MHz. Included in the package are the controllers, power switches, inductors, and support components. Operating over a wide input voltage range, the LTM8060 supports output voltages from 0.8V to 8V, and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the bulk input and output filter capacitors, are needed to finish the design. The LTM8060 product video is available on website.
The LTM8060 is packaged in a compact (11.9mm × 16mm × 3.32mm) over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8060 is available with SnPb (BGA) or RoHS compliant.
Configurable Output Array
The LTM8060 outputs can be paralleled in an array for up to 12A capability.

Demonstration circuit 2820A features the LTM8060 μModule® regulator, a quad output high-performance step-down Silent Switcher® μModule regulator in a thermally enhanced 11.9mm × 16mm × 3.32mm BGA package. DC2820A has a wide operating input voltage range of 5.4V to 40V. The output rails are configured for 5V, 3.3V, 1.5V, 1.2V and are resistor programmable from 0.8V to 8V. Each output can provide up to 3A and phases can also be paralleled together to satisfy higher rail current requirements. The LTM8060 is a complete multioutput DC/DC point of load regulator in a compact form factor, requiring only a few input and output capacitors and resistors to set the output voltages and operating frequency. Output voltage tracking is made available by the TRSS pins for supply rail sequencing. External clock synchronization is available through the SYNC pins, CLKOUT pins provide for optional synchronization of additional phases. For reduced noise, Spread Spectrum operation is available via SYNC pin programming. The LTM8060 data sheet must be read in conjunction with the DC2820A demo manual for working on or modifying demo circuit 2820A.
