28v, 2a, forced pwm synchronous step-down converter in sot23-6
description
features
eta8121 is a wide input range, high-efficiency 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 1mhz,
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. eta8121 also employs a forced pwm
control scheme, thereby ensuring the minimum
ripple voltage. its input can withstand a voltage
surge as high as 30v, making it an ideal solution
for industrial applications such as surveillance
camera, lcd tv, set top box, etc.
eta8121 is available in sot23-6 package.
