The LTM8060F is a quad 40VIN, 3A (4A peak) step-down Silent Switcher^® power μModule® (micromodule) regulator with package-level Electromagnetic interference (EMI) shield. The package-level EMI shield enables the Faraday cage to be applied directly to the LTM8060F package, and the EMI shield is electrically connected to the GND pins, providing a compact and effective near-field EMI reduction. The EMI shield eliminates all electric field noise, and a 10dB reduction is achieved on magnetic field noise. The Silent Switcher architecture minimizes EMI while delivering high efficiency.

Included in the package are the controllers, the power switches, the inductors, and the support components. Operating over a wide input voltage range, the LTM8060F 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 the output filter capacitors are needed to finish the design. The LTM8060F outputs can be paralleled in an array for up to 12A (16A peak) capability.

Product Details

The DC2820A-B evaluation board features the LTM^®8060F, a quad output high-performance step-down Silent Switcher® power μModule^® regulator in a thermally enhanced 16mm × 11.9mm × 2.9mm pre-soldered grid array (PSGA) package with a package-level electromagnetic interference (EMI) shield. The DC2820A-B has a wide operating input voltage range of 5.4V to 40V. The output rails are configured for 5V, 3.3V, 1.5V, and 1.2V. They 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 LTM8060F is a complete multi-output DC-to-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.

The CLKOUT pins provide for optional synchronization of additional phases. For reduced noise, spread spectrum operation is available through the SYNC pin programming. The LTM8060F data sheet must be read in conjunction with this user guide for working on or modifying the DC2820A-B.
