EC3221
Description
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 switching frequency.
Features
- low Rds(on) for internal switches (top/bottom):
- 3-5.5V input voltage range
- 1.5MHz switching frequency minimizes the external ponents
- Internal softstart limits the inrush current
- 100% dropout operation
- pact and thermally enhanced package:
SOP-8(Exposed PAD)
Applications
- LCD TV Wi Fi Card GPS
- Access Point Router
- Set Top Box
