3 / 30 page  LT8722 3 For more information www.analog.com Rev. 0 ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C, VIN = 15V, VDDIO = 3.3V and GND = SYNC = 0V, EN = SWEN = high unless otherwise specified. VCC has a 1μF capacitor to GND and is driven by the VCC regulator unless otherwise stated.
