TMI3359 1.5MHz, 30V, 1.2A FPWM Synchronous Step-Down Converter Features Description ⚫ Wide Input Range: 4.5V to 30V The TMI3359 is a high efficiency 1.5MHz, ⚫ Feedback Voltage: 0.8V±2% synchronous step-down DC-DC converter capable ⚫ 1.5MHz Switch Frequency of delivering up to 1.2A current with force PWM operation and adopts COT control with fast ⚫ Up to 1.2A Output Current transient response performance. TMI3359 ⚫ Force Constant Current PWM Operation integrates both high and low side switch with low ⚫ COT control to achieve fast transient RDS(ON) to minimize the conduction loss. Low output responses voltage ripple and small external inductor and ⚫ Integrated internal compensation capacitor size are achieved with 1.5MHz switching ⚫ Stable with Low ESR Ceramic Output frequency. Capacitors The TMI3359 requires a minimum number of ⚫ Over Current Protection with Hiccup Mode readily available standard external components ⚫ Thermal Shutdown and is available in a 6-pin SOT23-6 RoHS ⚫ Inrush Current Limit and Soft Start compliant package.
