Application Note 1557 Author: Jia Wei ISL62883CEVAL2Z User Guide Introduction Interface Connections The ISL62883CEVAL2Z evaluation board demonstrates the performance of the ISL62883 multiphase synchronous-buck PWM VCORE controller implementing Intel IMVP-6.5 protocol. The ISL62883 features Intersil's Robust Ripple Regulator (R3) technology. An on-board dynamic-load generator is included for evaluating the transient-load response. It applies a 300µs pulse of approximately 25mΩ load across VO and PGND. • VIN: Input Voltage to the Power Stage - J5: VIN Positive Power Input - TP31: VIN Positive Voltage Sense - J6: VIN Return Power Input - TP32: VIN Return Voltage Sense Contents of this document include: • Design Criteria • +5V: +5V Input Voltage - TP29: +5V Positive Input - TP30: +5V Return Input • Recommended Test Equipment • Interface Connections • Switch Descriptions • +12V: Input Voltage for the Dynamic-load Generator - TP3: 12V Positive Input - TP2: 12V Return Input • DIP Switch Descriptions • Jumper Descriptions • Test Point Descriptions J2 _ VO + VALUE UNITS 4.5 to 20 VDC 0 to 1.5 VDC 75 ADC 300 kHz Full-load PWM Frequency Recommended Equipment • (QTY 1) Adjustable 25V, 10A Power Supply • (QTY 1) Fixed 5V, 100mA Power Supply • (QTY 1) Fixed 12V, 100mA Power Supply • (QTY 1) Adjustable Constant Current Electronic Load • (QTY 1) Digital Voltmeter • (QTY 1) Four-Channel Oscilloscope 1 J6 PGND J3 D1 S1 0 0 U2 VIN TABLE 1.
