FEATURES
DESCRIPTION
The SC9301 supports using standard capacitor types such as electrolytic or specialty polymer, in addition to ceramic, at switching frequencies up to 1MHz. Additional features include programmable cycle-by-cycle current limit protection, programmable soft-start, under and over-voltage protection, automatic fault recovery (hiccup restart), and soft shutdown. The device also provides separate enable inputs for the PWM controller and LDO as well as a power good output for the PWM controller.●
