EC3221 Overview
The EC3221 are high-efficiency 1.5MHz synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A output currents, respectively. The EC3221 operates over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor And capacitor sizes are achieved with 1.5MHz...
EC3221 Key Features
- low Rds(on) for internal switches (top/bottom)
- 3-5.5V input voltage range -1.5MHz switching frequency minimizes
- pact and thermally enhanced package
