current. An active low shutdown pin typically reduces total

supply current to 35

µA 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.

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
