ILC6370

Impala Linear Corporation ILC 6370/71 SOT-89 Step up Switching Regulator with Shutdown General Description 50mA boost converter in 5-lead SOT-89 package. Only 3 external components are needed to complete the switcher design, and frequency options of 50, 100, and 180kHz gives the designer the ability to trade off system needs with switcher design size. 87% max duty cycle gives conversion efficiencies of 85%. Standard voltage options of 2.5V, 3.3V, and 5.0V at ±2.5% accuracy feature on-chip phase compensation and softstart design. ILC6371 drives an external transistor for higher current switcher design, with all of the features and benefits of the ILC6370. Features ! 85% efficiency at 50mA ! Start-up voltages as low as 900mV ! ±2.5% accurate outputs ! Complete switcher design with only 3 external components ! 50, 100 and 180kHz switching frequency versions available ! Shutdown to 0.5µA ! External transistor option allows several hundred milliamp switcher design Applications ! Cellul...
