MAX16840
LED Driver with Integrated MOSFET
for MR16 and Other 12V AC Input Lamps
ELECTRICAL CHARACTERISTICS (continued)
(V IN = 12V; V EXT = V SOURCE = V FB = V GND = 0V; COMP, REFI, and DRAIN = open; T A = T J = -40 N C to +125 N C, unless otherwise
noted. Typical values are at T A = +25 N C.) (Note 2)
