Evaluation Kit for the MAX5060 (MAX5060EVKIT) (MAX5060EVKIT)

The MAX5060 evaluation kit (EV kit) provides a +3.3V adjustable output voltage from a +12V input source. It delivers up to 20A of output current with a switching frequency of 270kHz and achieves efficiencies up to 93%.

The MAX5060 single-phase, PWM controller provides high-output-current capability in a compact package with a minimum number of external components. The MAX5060 utilizes average current-mode control that offers accurate current limit and current sharing, and avoids oversizing the MOSFETs and inductor.

Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with +4.75V to +5.5V, or +7V to +28V input-voltage ranges. The high switching frequency, up to 1.5MHz, allows the use of low inductor and input capacitor values. This accommodates the use of PCB-embedded planar magnetics, achieving superior reliability, current sharing, thermal management, compact size, and low system cost.

The MAX5060 also features a clock input (CLKIN) for synchronization to an external clock, and a clock output (CLKOUT) with 180° phase delay to control a second out-of-phase converter for lower-input-capacitor ripple current. The MAX5060 also limits the reverse current if the bus voltage becomes higher than the regulated output voltage. This device is specifically designed to limit current sinking when multiple power-supply modules are paralleled. The MAX5060 offers an adjustable +0.6V to +5.5V (VIN > 7V) output voltage.
