DESCRIPTION
LT1182/LT1183/LT1184/LT1184F
LT1184/LT1184F pin out the reference for simplified pro-
gramming of lamp current.
The LT1182/LT1183/LT1184/LT1184F operate with input
supply voltages from 3V to 30V. The ICs also have a
battery supply voltage pin that operates from 4.5V to 30V.
The LT1182/LT1183 draw 9mA typical quiescent current
while the LT1184/LT1184F draw 6mA typical quiescent

current. An active low shutdown pin typically reduces total
supply current to 35 A for standby operation. A 200kHz
switching frequency minimizes the size of required mag-
netic components. The use of current mode switching
techniques with cycle-by-cycle limiting gives high reliabil-
ity and simple loop frequency compensation. The LT1182/
LT1183/LT1184/LT1184F are all available in 16-pin nar-
row SO packages.
