LTM4606
ELECTRICAL CHARACTERISTICS The l denotes the speciļ¬cations which apply over the full internal
operating temperature range, otherwise speciļ¬cations are at TA = 25°C. VIN = 12V, unless otherwise noted. Per typical application
(front page) conļ¬guration, RFB = 40.2k.

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 LTM4606E is guaranteed to meet performance speciļ¬cations
over the 0°C to 125°C internal operating temperature range. Speciļ¬cations
over the ā40°C to 125°C internal operating temperature range are assured
by design, characterization and correlation with statistical process
controls. The LTM4606I is guaranteed to meet speciļ¬cations over the
ā40°C to 125°C internal operating temperature range. The LTM4606MP
is guaranteed and tested over the ā55°C to 125°C internal operating
temperature range. Note that the maximum ambient temperature is
determined by speciļ¬c operating conditions in conjunction with board
layout, the rated package thermal resistance and other environmental
factors.
Note 3: 100% tested at die level only.
Note 4: See output current derating curves for different VIN, VOUT and TA.
