4 / 11 page RT7247CHGSP Evaluation Board UG7247CHGSP-00 July 2014 www.richtek.com 4 Bench Test Setup Conditions Headers Description and Placement Please carefully inspect the EVB IC and external components, comparing them to the following Bill of Materials, to ensure that all components are installed and undamaged. If any components are missing or damaged during transportation, please contact the distributor or send e-mail to evb_service@richtek.com. Test Points The EVB is provided with the test points and pin names listed in the table below. Test point/ Pin name Signal Comment (expected waveforms or voltage levels on test points) VIN Input voltage Input voltage range= 4.5V to 18V VOUT Output voltage Default output voltage = 3.3V Output voltage range= 0.8V to 12V (see ‘’ Output Voltage Setting’’ section for changing output voltage level) SW Switching node test point SW waveform EN Enable test point Enable signal. EN is automatically pulled high (by R4) to enable operation. Connect EN low to disable operation. BS Boot strap supply test point Floating supply voltage for the high-side N-MOSFET switch SS Soft-start control test point Soft start waveform GND Ground Ground |
