钰泰 ETA8121 SOT23-6 电池充电管理芯片

DESCRIPTION
ETA8l21is a wide input range. high-fficiency and high frequency 
DC-to-DC step-down switching regulator capable of delivering 
up to 2A of output current. With a fixed switching frequency of
MHz, this current mode PWM controlled converter allows the
use of small external components, such as ceramic input and
output caps, as well as small inductors. E TA8121 also employs a
forced PWM control scheme, thereby ensuring the minimum
ripple voltage. Its input can withstand a voltage surge as high
as 3QV. making it an ideal solution for industrial applications
such as Sureilance Camera, LCDTV. Set Top Box, etc.
ETA8121 is available in SOT23-6 package.
