FAQ

What is the primary function of the MAX20011GEVKIT#?

The MAX20011GEVKIT# is a dedicated evaluation platform for the MAX20011G 16A automotive buck regulator. It provides immediate out-of-box validation of key performance metrics including load transient response, efficiency across input/output conditions, I²C programmability, and loop stability. The board is fully assembled with optimized PCB layout, remote sensing, and test points enabling precise measurement without modification.

Does the MAX20011GEVKIT# support dynamic output voltage adjustment?

Yes, the MAX20011GEVKIT# supports full dynamic output voltage adjustment via its onboard I²C interface (J1). Using compatible hardware like MINIQUSB and SimpleI2C software, users can program the MAX20011G's output from 0.5V to 1.275V in precise 6.25mV steps and configure programmable slew rates-enabling real-time core voltage scaling tests for automotive SoCs.

How is remote voltage sensing implemented on the MAX20011GEVKIT#?

Remote voltage sensing on the MAX20011GEVKIT# uses dedicated differential sense points RS+ (J10) and RS− (J29), directly connected to the MAX20011G's feedback network. This configuration compensates for PCB trace resistance between the regulator and load, ensuring accurate regulation at the point of load. J10 is explicitly designated as the primary sense-point measurement location for ripple and transient analysis.

Can the MAX20011GEVKIT# be synchronized to an external clock?

Yes, the MAX20011GEVKIT# supports external synchronization via jumper J4, which connects to the MAX20011G's SYNC pin. Users can apply a 50% duty-cycle square wave to synchronize switching frequency-critical for noise-sensitive multi-rail systems or EMI testing. The default operation remains 2.2MHz fixed-frequency PWM unless externally overridden.

What test equipment is required to operate the MAX20011GEVKIT#?

To operate the MAX20011GEVKIT#, you need a 3V–5.5V DC power supply (rated ≥20A), an electronic or resistive load capable of drawing up to 16A, voltmeters for input/output/RESETB monitoring, an ammeter for input current, and optionally a differential probe for ripple/transient measurements at J10. Loop analysis requires a signal generator and oscilloscope connected to J27/J28.
