ISL6263C Datasheet, PDF (7/18 Pages) Intersil Corporation – 5-Bit VID Single-Phase Voltage Regulator with Current Monitor for GPU Core Power

ISL6263C
Electrical Specifications
These specifications apply for T_A = -10°C to +100°C, unless otherwise stated.
All typical specifications T_A = +25°C, V_DD = 5V, PVCC = 5V. Boldface limits apply over the operating
temperature range, -10°C to +100°C. (Continued)
