Evaluation Kit for the MAX5065 (MAX5065EVKIT) (MAX5065EVKIT)
The MAX5065 evaluation kit (EV kit) provides a +1.3V adjustable output voltage from a +12V input source. It delivers up to 10A of output current with a switching frequency of 250kHz per phase and achieves efficiencies up to 85%.
The MAX5065 dual-phase, PWM controller provides high-output-current capability in a compact package with a minimum number of external components. The MAX5065 utilizes a dual-phase, average current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents.
Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with input voltage ranges of +4.5V to +5.5V or +8V to +28V. The high switching frequency and dualphase operation allow the use of low-output inductor values and input capacitor values. This accommodates the use of PC-board-embedded planar magnetics achieving superior reliability, current sharing, thermal management, compact size, and low system cost.
The MAX5065 also features a clock input (CLKIN) for synchronization to an external clock, and a clock output (CLKOUT) with programmable phase delay (relative to CLKIN/DH) for paralleling multiple phases. The MAX5065 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 MAX5065 offers an adjustable +0.6V to +3.3V output voltage.
