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.
