TJMAX = 125°C, θJA = 40°C/W (NOTE 3)

EXPOSED PAD (PIN 11) IS GND, MUST BE SOLDERED TO PCB

Consult LTC Marketing for parts speciﬁed with wider operating temperature ranges.

LTC4076EDD

(Notes 1, 7)

The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VDCIN = 5V, VUSBIN = 5V, HPWR = 5V unless otherwise noted.
