ECT3409 Dual Channel 600mA, 1.5MHz Step-Down Converter Description The ECT 3409 is a dual channel cur- rent mode PWM DC-DC step -down conv erter o perating at 1.5 MHz constant fre quency. The device is i deal for p ortable equipment requiring two sep arate po wer su pplies that need high current up to 600mA. The device operates from single-cell Lit hium-ion batt eries whil e st ill achieving over 96% efficiency. The ECT3409 al so can run at 100% duty cycle fo r low dropo ut ope ration, exten ding battery l ife in portable systems while light load o peration provides very low output ripple for noise sensitive applications.
