These EV kits operate from a -8V to These EV kits are fully assembled and tested. Follow the -60V input voltage range and supports output voltage steps below to verify board operation. range of 3.3V to 60V. These EV kits use the MAX15158, MAX15158A, and MAX15158Z on a proven six-layer Caution: Do not turn on the power supply until all PCB design. Two pieces of MAX15013 are used as the connections are completed. MOSFET driver for the EV kits. These EV kits also feature 1) Verify that a shunt is installed across jumpers J3 and J4. an on-board buck converter (MAX17552) to provide 10V 2) Verify that a shunt is installed between pins 2 and 3 supply voltage to MAX15158/MAX15158A/MAX15158Z on jumper J6. and the MOSFET driver. 3) Turn on power-supply PS1 and set the supply to 48V, Features then disable the power supply. -8V to -60V Input Voltage Range for Inverting Buck- 4) Connect the positive terminal of power-supply PS1 Boost Configuration to the VIN+ banana jack on the EV kit.

BODE+ and BODE- proven designs to evaluate the MAX15158, MAX15158A, test points are provided on the board on either side of 10 and MAX15158Z fully integrated, highly efficient, two- resistor for small-signal injection and ability to measure phase switching regulators. These EV kits can be easily bode plot. connected between power input and the load using the banana jacks and connectors provided for the input Output Regulation and output. Test points and connectors are provided to VOUT P and VOUT N test points are provided to monitor and control the device signals. These EV kits measure the VOUT regulation. operate between -8V and -60V input voltages. These EV kits regulate the output voltage between 3.3V and Efficiency Measurement 60V. The output voltage is set to 35V by default on the V and V are provided to measure V during IN P IN N IN EV kits. The output voltage can be changed by changing efficiency measurement. Also, V and V are OUT P OUT N resistor divider between VOUT+ pin and OUTP pin. Make provided to measure V during efficiency measurement. OUT sure that the correct compensation is selected for stable operation. FREQ/CLK Pin Switching frequency is selected by connecting R16 resistor EN/UVLO Input for the MAX15158/MAX15158A/ between FREQ/CLK pin and VIN-. The switching MAX15158Z frequency can also be selected by providing a 480kHz to The devices enable input (EN/UVLO) is controlled by 4MHz external clock at this pin. A test point (CLOCK) is resistor divider ratio between R19 and R20. The divider also provided to drive this pin. ratio is chosen so that the VIN UVLO threshold is set at 21V by default. If EN/UVLO pin voltage is above REFIN Pin (MAX15158/MAX15158Z) 1V, MAX15158/MAX15158A/MAX15158Z will power up. By default, REFIN pin is connected to BIAS supply EN/UVLO pin can be connected to VIN- to disable the through R9 (0 resistor). R9 can be removed and REFIN regulation. Additionally, a test point (EN) is also can be connected to external supply (between 1V to 2.2V) provided to drive the EN/UVLO pin. While changing the to change the VOUT reference and therefore change UVLO threshold, make sure that the UVLO threshold of output regulation voltage.
