DC2215A

製品概要

Demonstration Circuit 2215A, features the LTC3126, a synchronous buck converter with an integrated lossless input PowerPath™. Pin selectable (JP2) ideal diode-OR and priority input modes, with programmable undervoltage lockout thresholds provide control over the transition between input sources. The unique all N-channel architecture provides efficient operation from either of two input sources to a programmable output voltage. In this application the valid input voltage range is set to be from 4.3V to 42V on V_IN1 and from 6V to 8.4V on V_IN2 providing flexibility and voltage margin for a variety of applications and power sources. V_IN2 can operate to 42V. Other input voltage ranges are possible by adjusting the V_SET1/2 threshold values (set by resistors R9 thru R12) accordingly.
