ELECTRICAL CHARACTERISTICS The ● denotes the speciﬁcations which apply over the full internal

operating temperature range, otherwise speciﬁcations are at TA = 25°C. VIN = 5V unless otherwise noted. See Figure 1.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LTM4608AE is guaranteed to meet performance

speciﬁcations over the 0°C to 125°C internal operating temperature

range. Speciﬁcations over the full –40°C to 125°C internal operating

temperature range are assured by design, characterization and

correlation with statistical process controls. The LTM4608AI is

guaranteed to meet speciﬁcations over the full internal operating

temperature range. The LTM4608AMP is guaranteed and tested

over the –55°C to 125°C temperature range. Note that the maximum

ambient temperature is determined by speciﬁc operating conditions in

conjunction with board layout, the rated package thermal resistance and

other environmental factors.

Note 3: See output current derating curves for different VIN, VOUT and TA.
