Product Details
The EVAL-RHM4900-AZ evaluation board features the RHM4900, a quad output, high-performance, step-down Silent Switcher® power μModule® regulator in a thermally-enhanced 16mm × 11.9mm × 3.32mm, ball-grid array (BGA) package. The EVAL-RHM4900-AZ 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 RHM4900 is a complete multi-output, DC-to-DC, point-of-load (POL) 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 the optional synchronization of additional phases. For reduced noise, spread-spectrum operation is available through the SYNC pin programming. The RHM4900 data sheet must be read in conjunction with this user guide for working on or modifying the EVAL-RHM4900-AZ.
