General Description

The FTD6821 are high-efficiency 1.5MHz synchronous

step-down DC-DC regulator ICs capable of delivering

up to 1.5A output currents, respectively.

The FTD6821 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 components

Internal softstart limits the inrush current

100% dropout operation

Compact and thermally enhanced package:

SOP8-PP

Applications

LCD TV WiFi

Card GPS

Access Point Router

Set Top Box
