LTM8060 Silent Switcher Regulator

ADI's LTM8060's silent switcher architecture minimizes EMI emissions, enabling it to pass the CISPR 22 Class B standard with no input filter. This is critical for noise-sensitive applications such as signal processing in medical imaging and RF. Furthermore, its multi-output capability allows users to use the LTM8060 for a variety of voltage and load 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 DC2820A features the LTM8060 μModule regulator, a quad output high-performance step-down Silent Switcher® μModule regulator in a thermally-enhanced 11.9 mm x 16 mm x 3.32 mm BGA package. DC2820A has a wide operating input voltage range of 5.4 V to 40 V. The output rails are configured for 5 V, 3.3 V, 1.5 V, and 1.2 V and are resistor programmable from 0.8 V to 8 V. Each output can provide up to 3 A and phases can also be paralleled together to satisfy higher rail current requirements.
