SC9301

SC9301 10A EcoSpeed® Integrated FET Regulator with 5V LDO and Hiccup Restart POWER MANAGEMENT Features „ Description The SC9301 is a stand-alone synchronous EcoSpeed® buck regulator with adaptive on-time control architecture. It features integrated power MOSFETs, a bootstrap switch, and a fixed 5V LDO in a 5x5mm package. The device is highly efficient and uses minimal PCB area. 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. Power system Input voltage — 3V to 28V Bias Voltage — 5V LDO or 3V to 5.5V external Up to 96% peak efficiency Integrated bootstrap switch LDO output current — up to 200mA Reference tolerance — 1% TJ= -40 to +125 °C „ „ „ „ „ „ „ EcoSpeed® architecture with pseudo-fixed frequency adaptive on-time control Pre-bias start-up Logic input and output control Independent enable control for LDO and switcher Programmable VIN UVLO threshold Power good output Programmable soft-start time All protection: automatic restart on fault Over-voltage and under-voltage TC compensated RDS(ON) sensed current limit Therma...
