ILC6380 Datasheet (Impala Linear Corporation) - SOT-89 STEP-UP DUAL-MODE SWITCHER

ILC6380, SOT-89 STEP-UP DUAL-MODE SWITCHER

100mA boost converter in 5-lead SOT-89 package using both PFM and PWM conversion techniques.

In normal operation the ILC6380 runs in PWM mode running at one of three fixed frequencies.

At light loads the ILC6380 senses when the duty cycle drops to approximately 10%, and automatically switches into a
