ISL62873 Datasheet, PDF (6/17 Pages) Intersil Corporation – PWM DC/DC Controller with VID Inputs for Portable GPU Core-Voltage Regulator

ISL62873
Electrical Specifications
These specifications apply for T_A = -10°C to +100°C, unless otherwise stated.
All typical specifications T_A = +25°C, VCC = 5V. Parameters with MIN and/or MAX limits are 100% tested at
+25°C, unless otherwise specified. Temperature limits established by characterization and are not production
tested. (Continued)
