RT8096C 1A, 1.5MHz, 6V CMCOT Synchronous Step-Down Converter General Description Features Efficiency Up to 95% The RT8096C is a high efficiency synchronous step- R 160m HS / 110m LS DSON down DC/DC converter. Its input voltage range is from V Range 2.5V to 6V IN 2.5V to 6V and provides an adjustable regulated output V 0.6V with 2% Accuracy REF voltage from 0.6V to 3.4V while delivering up to 1A of CMCOT Control Loop Design for Best output current. Transient Response, Robust Loop Stability with The internal synchronous low on-resistance power Low-ESR (MLCC) C OUT switches increase efficiency and eliminate the need for Fixed Soft-Start 1.2ms PGOOD Function in an external Schottky diode. The Current Mode TSOT-23-6 Constant-On-time (CMCOT) operation with internal Cycle-by-Cycle Over Current Protection compensation allows the transient response to be Input Under Voltage Lockout optimized over a wide range of loads and output Output Under Voltage Protection (UVP Hiccup) capacitors. The RT8096C is available in the TSOT-23- Thermal Shutdown Protection 5 and TSOT-23-6 packages.
